Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Description of Business Westell Technologies, Inc. (the Company) is a holding company. Its wholly owned subsidiary, Westell, Inc., designs and distributes telecommunications products, which are sold primarily to major telephone companies. Basis of Presentation and Reporting The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. The Condensed Consolidated Financial Statements have been prepared using generally accepted accounting principles (GAAP) in the United States for interim financial reporting, and consistent with the instructions of Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2019 . All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited interim financial statements included herein reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s condensed consolidated financial position and the results of operations, comprehensive income (loss) and cash flows at June 30, 2019 , and for all periods presented. The results of operations for the periods presented are not necessarily indicative of the results that may be expected for fiscal year 2020 . Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and that affect revenue and expenses during the periods reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, intangible assets fair value, depreciation, income taxes, right-of-use lease assets and related lease liabilities, and contingencies, among other things. Actual results could differ from those estimates. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (ASU 2016-02). In September 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842) (ASU 2017-13), which provides additional implementation guidance on ASU 2016-02. ASU 2016-02 requires lessees to recognize leases on the balance sheet as right-of-use assets, representing the right to use the underlying asset for the lease term, and a corresponding lease liability for leases with terms greater than one year. The liability will be equal to the present value of lease payments while the right-of-use asset will be based on the liability, subject to adjustment, such as prepaid lease payments. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842 (Leases) , which provides narrow amendments to clarify how to apply certain aspects of the new lease standard. In July 2018, the FASB also issued ASU 2018-11, Targeted Improvements . The amendments in this ASU provide for an additional transition method in which an entity applying the lease standard at adoption date recognizes a cumulative-effect adjustment to the opening balance of retained earnings (deficit) in the period of adoption. The Company adopted the lease standard on April 1, 2019, using the modified retrospective method. Under this method, the new guidance would apply to existing and new leases on the date of initial application while comparative prior periods would be reported in accordance with the Topic 840 guidance effective prior to April 1, 2019, and requiring no retrospective adjustments. Upon adoption, total assets and liabilities increased due to recording the right-of-use assets of $1.3 million and lease liabilities of $1.2 million . Refer to Note 2 for additional disclosures around leases. In July 2018, the FASB issued ASU 2018-09, Codification Improvements (ASU 2018-09). ASU 2018-09 does not prescribe any new accounting guidance, but instead makes minor improvements and clarifications of several different FASB Accounting Standards Codification areas based on comments and suggestions made by various stakeholders. The Company adopted ASU 2018-09 effective April 1, 2019. The amendments had no impact to the Company's Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (ASU 2018-13). This update modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. Certain disclosure requirements established in Topic 820 have been removed, some have been modified and new disclosure requirements were added. This new standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2018-13 may have on the Company’s Condensed Consolidated Financial Statements and related disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (ASU 2018-15). The main objective of ASU 2018-15 is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments in this update require that a customer in a hosting arrangement that is a service contract follow the guidance in Subtopic 350-40 to determine which implementation costs should be capitalized as an asset and which costs should be expensed and states that any capitalized implementation costs should be expensed over the term of the hosting arrangement. This new standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2018-15 may have on the Company’s Condensed Consolidated Financial Statements. In November 2018, the FASB issued ASU 2018-18 Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 (ASU 2018-18). The update provides guidance on the interaction between Revenue Recognition (Topic 606) and Collaborative Arrangements (Topic 808) by aligning the unit of account guidance between the two topics and clarifying whether certain transactions between collaborative participants should be accounted for as revenue under Topic 606. ASU 2018-18 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2018-18 may have on the Company's Condensed Consolidated Financial Statements.

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	Leases The Company adopted ASC 842 effective April 1, 2019, which resulted in an increase to total assets of $1.3 million to record the right-of-use (ROU) assets for operating leases of facilities and an increase in total liabilities of $1.2 million to record the associated lease liabilities. The difference between operating lease liabilities and ROU assets recognized is primarily due to prepaid rent and deferred rent accruals recorded under prior lease accounting standards. ASC 842 requires such balances to be reclassified against ROU assets at transition. In future periods such balances will not be presented separately. The adoption did not have any impact on the Company's Condensed Consolidated Statements of Operations or the Condensed Consolidated Statements of Cash Flows. ROU assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the net present value of remaining fixed lease payments over the lease term. Lease terms used to calculate the present value of the lease payments include any options to extend, renew, or terminate the lease, when it is reasonably certain that these options will be exercised. ROU assets also include any advance lease payments made and exclude any lease incentives. As the implicit interest rate for our leases is not readily determinable, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease arrangements with non-lease components that are not in-substance fixed and considered variable, which were not included in the carrying balances of the right-of-use asset and lease liability. The Company does not have any finance leases. The Company elected the package of practical expedients, which among other things, allows the Company to carry forward historical lease classifications. Leases with an initial term of 12 months or less are not recorded on the Condensed Consolidated Balance Sheets. The Company also made the accounting policy election to account for each separate lease component and non-lease component associated with that lease component as a single lease component, thus causing all fixed payments to be capitalized. The Company determines at inception whether an arrangement is a lease. The Company reviews the impairment ROU assets consistent with the approach applied to other long-lived assets. ROU assets are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the asset’s carrying amount over its fair value. The Company's operating leases primarily include building leases for the corporate headquarters in Aurora, IL, an engineering and service center in Dublin, OH, and office space in Manchester, NH. Future minimum lease payments as of June 30, 2019 , consisted of the following (in thousands): Fiscal Year Operating Leases 2020 (1) $ 608 2021 478 2022 73 Thereafter — Total lease payments (2) 1,159 Less: imputed interest (38 ) Total operating lease liabilities $ 1,121 _______ (1) Represents the future minimum operating lease payments expected to be made over the remaining balance of the fiscal year. (2) Assumes exercise of a two year option to extend the lease term for the Dublin lease. As of June 30, 2019 , the weighted-average remaining lease term was 1.3 years and the weighted-average discount rate was 4.3% . Lease expenses are included in Cost of revenue, Sales and marketing, Research and development, and General and administrative in the Company's Condensed Consolidated Statements of Operations. The components of lease expense are as follows: (in thousands) Three months ended June 30, 2019 Operating lease expense $ 204 Variable lease expense (1) 40 Total Lease expense (2) $ 244 _______ (1) Variable lease expense is related to our leased real estate in Ohio and New Hampshire and primarily includes labor and operational costs as well as taxes and insurance. (2) Short-term lease expense is immaterial. For the three months ended June 30, 2019 , cash paid for operating leases included in the measurement of lease liabilities was $0.1 million . All of these payments are presented in Operating activities cash flows on the Condensed Consolidated Statements of Cash Flows. The following table summarizes the classification of ROU assets and lease liabilities as of June 30, 2019 : (in thousands) June 30, 2019 Balance Sheet Classification Assets: Total ROU assets $ 1,111 Right-of-use assets on operating leases, net Liabilities: Current operating lease liability 785 Accrued expenses Non-current operating lease liabilities 336 Other non-current liabilities Total lease liabilities $ 1,121

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Recognition and Deferred Revenue The Company records revenue based on a five-step model in accordance with ASC Topic 606, Revenue From Contracts With Customers (ASC 606). The Company's revenue is derived from the sale of products, software, and services identified in contracts. A contract exists when both parties have an approved agreement that creates enforceable rights and obligations, identifies performance obligations and payment terms and has commercial substance. The Company records revenue from these contracts when control of the products or services transfer to the customer. The amount of revenue to be recognized is based upon the consideration, including the impact of any variable consideration, that the Company expects to be entitled to receive in exchange for these products and services. Disaggregation of revenue The following table disaggregated our revenue by major source: (In thousands) Three months ended June 30, 2019 2018 Revenue: Products $ 7,815 $ 11,789 Software 19 416 Services 1,168 832 Total revenue $ 9,002 $ 13,037 The following is the expected future revenue recognition timing of deferred revenue as of June 30, 2019 : < 1 year 1-2 years > 2 years Deferred Revenue $ 950 $ 219 $ 174 During the three months ended June 30, 2019 , and June 30, 2018, the Company recognized $0.4 million and $0.5 million of revenue, respectively, related to contract liabilities at the beginning of the periods. The Company allows certain customers to return unused product under specified terms and conditions. The Company estimates product returns based on historical sales and return trends and records a corresponding refund liability. The refund liability is included within Accrued expenses on the accompanying Condensed Consolidated Balance Sheets. Additionally, the Company records an asset based on historical experience for the amount of product we expect to return to inventory as a result of the return, which is recorded in Prepaid and other current assets in the Condensed Consolidated Balance Sheets. The gross product return asset was $0.1 million and $0.1 million at June 30, 2019 , and June 30, 2018, respectively.

Segment Reporting [Abstract]
Interim Segment Information	Interim Segment Information Segment information is presented in accordance with a “management approach", which designates the internal reporting used by the chief operating decision-maker (CODM) for making decisions and assessing performance as the source of the Company's reportable segments. Westell’s Chief Executive Officer is the CODM. The CODM continues to define segment profit as gross profit less research and development expenses. The accounting policies of the segments are the same as those for Westell Technologies, Inc. described in the summary of significant accounting policies included in the Company's Annual Report on Form 10-K for year ended March 31, 2019, and as updated in this filing. The Company’s three reportable segments are as follows: In-Building Wireless (IBW) Segment The IBW segment solutions enable cellular coverage in stadiums, arenas, malls, buildings, and other indoor areas not served well or at all by the existing "macro" outdoor cellular network. For commercial service, solutions include distributed antenna systems (DAS) conditioners and digital repeaters. For the public safety market, solutions include half-watt and two-watt repeaters and a battery backup unit. IBW also offers ancillary products that consist of passive system components and antennas for both the commercial and public safety markets. In addition, in fiscal year 2019, IBW, in partnership with ip.access, a leading small cell solutions partner based in the U.K., began developing an OnGo small cell for the private LTE market. Intelligent Site Management (ISM) Segment ISM segment solutions include a suite of remote units, which are network devices used for on-site processing. Remotes provide on-site machine-to-machine (M2M) communications that enable operators to remotely monitor, manage, and control site infrastructure and support systems. Remotes can be and often are combined with our Optima management software system. ISM also offers support services (i.e., maintenance agreements) and deployment services (i.e., installation). Communications Network Solutions (CNS) Segment CNS segment solutions include a broad range of outdoor network infrastructure offerings consisting of integrated cabinets, power distribution products, copper and fiber network connectivity panels, fiber access products, T1 network interface units (NIUs), and tower mounted amplifiers (TMAs). Segment information for the three months ended June 30, 2019 , and 2018 , is set forth below: Three months ended June 30, 2019 (in thousands) IBW ISM CNS Total Revenue $ 2,923 $ 3,095 $ 2,984 $ 9,002 Cost of revenue 1,951 1,516 2,289 5,756 Gross profit 972 1,579 695 3,246 Gross margin 33.3 % 51.0 % 23.3 % 36.1 % Research and development 399 701 456 1,556 Segment profit $ 573 $ 878 $ 239 1,690 Operating expenses: Sales and marketing 2,332 General and administrative 1,364 Intangible amortization 308 Operating profit (loss) (2,314 ) Other income, net 164 Income tax benefit (expense) (7 ) Net income (loss) $ (2,157 ) Three months ended June 30, 2018 (in thousands) IBW ISM CNS Total Revenue $ 3,557 $ 5,744 $ 3,736 $ 13,037 Cost of revenue 1,895 2,796 2,411 7,102 Gross profit 1,662 2,948 1,325 5,935 Gross margin 46.7 % 51.3 % 35.5 % 45.5 % Research and development 522 569 341 1,432 Segment profit (loss) $ 1,140 $ 2,379 $ 984 4,503 Operating expenses: Sales and marketing 2,137 General and administrative 1,534 Intangible amortization 990 Operating profit (loss) (158 ) Other income, net 119 Income tax benefit (expense) — Net income (loss) $ (39 ) Segment asset information is not reported to or used by the CODM.

The stock options, restricted stock awards, and restricted stock units (RSUs) awarded under the 2015 Plan generally vest in equal annual installments over 3 years for employees and 1 year for non-employee directors. Performance stock units (PSUs) earned vest over the performance period. Certain awards provide for accelerated vesting if there is a change in control (as defined in the 2015 Plan), or when provided within individual employment contracts. The Company accounts for forfeitures as they occur. The Company issues new shares for stock awards under the 2015 Plan. The following table is a summary of total stock-based compensation expense resulting from stock options, restricted stock, RSUs and PSUs, during the three months ended June 30, 2019 , and 2018 : Three months ended June 30, (in thousands) 2019 2018 Stock-based compensation expense $ 244 $ 291 Income tax benefit — — Total stock-based compensation expense, after taxes $ 244 $ 291 Stock Options Stock option activity for the three months ended June 30, 2019 , is as follows: Shares Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (1) (in thousands) Outstanding on March 31, 2019 293,478 $ 4.28 4.4 $ — Granted — — Exercised — — Forfeited — — Expired (7,500 ) 8.58 Outstanding on June 30, 2019 285,978 $ 4.17 4.2 $ — _______ (1) The intrinsic value for the stock options is calculated based on the difference between the exercise price of the underlying awards and the Westell Technologies’ closing stock price as of the respective reporting date.

Product Warranties Disclosures [Abstract]
Product Warranties	Product Warranties The Company’s products carry a limited warranty ranging from one to five years for the products within the IBW segment, typically one year for products within the ISM segment (formerly ISMS), and one to seven years for products within the CNS segment. The specific terms and conditions of those warranties vary depending upon the customer and the products sold. Factors that affect the estimate of the Company’s warranty reserve include: the number of units shipped, anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the reserve as necessary. The current portions of the warranty reserve are $84,000 and $74,000 as of June 30, 2019 , and March 31, 2019 , respectively, and are presented on the Condensed Consolidated Balance Sheets in Accrued expenses. The non-current portions of the warranty reserves are $46,000 and $56,000 as of June 30, 2019 , and March 31, 2019 , respectively, and are presented on the Condensed Consolidated Balance Sheets in Other non-current liabilities. The following table presents the changes in the Company’s product warranty reserve: Three months ended June 30, (in thousands) 2019 2018 Total product warranty reserve at the beginning of the period $ 130 $ 300 Warranty expense to cost of revenue 12 20 Utilization (12 ) (30 ) Total product warranty reserve at the end of the period $ 130 $ 290

Guarantees [Abstract]
Equity Method Investment [Text Block]	Variable Interest Entity and Guarantee The Company has a 50% equity ownership in AccessTel Kentrox Australia PTY LTD (AKA). AKA distributes network management solutions provided by the Company and the other 50% owner to one customer. The Company holds equal voting control with the other owner. All actions of AKA are decided at the board level by majority vote. The Company evaluated ASC 810, Consolidations , and concluded that AKA is a variable interest entity (VIE) and the Company has a variable interest in the VIE. The Company has concluded that it is not the primary beneficiary of AKA and, therefore, consolidation is not required. The carrying amount of the Company's investment in AKA was approximately $0.1 million as of June 30, 2019 , and March 31, 2019 , which is presented on the Condensed Consolidated Balance Sheets within Other non-current assets. The Company's revenue from sales to AKA for the three months ended June 30, 2019 , and 2018 , was $0.4 million and $0.6 million , respectively. Accounts receivable from AKA was $0.3 million and $0.3 million as of June 30, 2019 , and March 31, 2019 , respectively. Deferred revenue, which primarily relates to AKA maintenance contracts, was $0.7 million and $0.8 million as of June 30, 2019 , and March 31, 2019 , respectively. The Company also has provided an unlimited guarantee for the performance of the other 50% owner in AKA, which primarily provides support and engineering services to the customer. This guarantee was put in place at the request of the AKA customer. The guarantee, which is estimated to have a maximum potential future payment of $0.7 million , will stay in place as long as the contract between AKA and the customer is in place. The Company would have recourse against the other 50% owner in AKA in the event the guarantee is triggered. The Company determined that it could perform on the obligation it guaranteed at a positive rate of return and, therefore, did not assign value to the guarantee. The Company's exposure to loss as a result of its involvement with AKA, exclusive of lost profits, is limited to the items noted above.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim period, the Company makes its best estimate of the effective tax rate expected to be applicable for the full fiscal year and uses that rate to provide for income taxes on a current year-to-date basis before discrete items. If a reliable estimate cannot be made, the Company may make a reasonable estimate of the annual effective tax rate, including use of the actual effective rate for the year-to-date. The impact of discrete items is recorded in the quarter in which they occur. The Company utilizes the liability method of accounting for income taxes and deferred taxes, which are determined based on the differences between the financial statements and tax basis of assets and liabilities given the enacted tax laws. The Company evaluates the need for valuation allowances on the net deferred tax assets under the rules of ASC 740, Income Taxes. In assessing the realizability of the Company's deferred tax assets, the Company considers whether it is more likely than not that some or all of the deferred tax assets will be realized through the generation of future taxable income. In making this determination, the Company assessed all of the evidence available at the time, including recent earnings, forecasted income projections and historical performance. The Company determined that the negative evidence outweighed the objectively verifiable positive evidence and previously recorded a full valuation allowance against deferred tax assets. The Company will continue to reassess realizability going forward. As of June 30, 2019 , the Company had net deferred tax assets of approximately $39.0 million before a valuation allowance of $39.0 million . As of June 30, 2019, and March 31, 2019, the Company has $697,000 tax receivable associated with a prior AMT credit carryforward. The Company expects to recover the entire amount by 2022 via a tax refund. The Company recorded $7,000 of income tax expense in the three months ended June 30, 2019 , using an effective income tax rate of (0.30)% plus discrete items. The Company recorded $0 of income tax expense in the three months ended June 30, 2018 , using an effective rate of (0.64)% plus discrete items. The effective rate in both periods is impacted by the intraperiod allocation as a result of income or loss from continuing operations, and states which base tax on gross margin and not pretax income.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation and Contingency Reserves The Company and its subsidiaries are involved in various assertions, claims, proceedings and requests for indemnification concerning intellectual property, including patent infringement suits involving technologies that may be incorporated in the Company’s products, which are being handled and defended in the ordinary course of business. These matters are in various stages of investigation and litigation, and they are being vigorously defended. Although the Company does not expect that the outcome in any of these matters, individually or collectively, will have a material adverse effect on its financial condition or results of operations, litigation is inherently unpredictable. Therefore, judgments could be rendered, or settlements entered, that could adversely affect the Company’s operating results or cash flows in a particular period. The Company routinely assesses all of its litigation and threatened litigation as to the probability of ultimately incurring a liability, and it records its best estimate of the ultimate loss in situations where it assesses the likelihood of loss as probable. In the ordinary course of operations the Company receives claims where the Company believes an unfavorable outcome is possible and/or for which is probable and no estimate of possible losses can currently be made. A significant customer was a defendant in two patent infringement claims and is asserting possible indemnity rights under contracts with the Company. The customer has settled one matter, and initially won summary judgment for all claims in the other, but on appeal the decision was reversed. The customer has informed the Company that the customer intends to seek to recover from the Company a share of the settlement and defense costs. For the summary judgment case, the customer provided an initial allocation of their defense costs. During the fourth quarter of fiscal 2019, the Company obtained additional information to evaluate the facts for both cases and has agreed in principle to a combined settlement in the amount of $0.3 million . The parties have agreed to a settlement in which some indemnity rights are reserved, and under which payment is due by December 15, 2019. As of June 30, 2019, and March 31, 2019, the combined settlement is unpaid and accrued on the Condensed Consolidated Balance Sheets presented in Accrued expenses. Both of these claims relate to a business which was previously sold and therefore any future expense would be presented as discontinued operations. Leases The Company leases office space under operating leases, with various expiration dates through September 30, 2020. The terms of some of the Company’s office leases provide for rental payments on a graduated scale. Lease expense is recognized on a straight-line basis over the lease term. For further details, refer to Note 2 . Leases.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined by ASC 820, Fair Value Measurements and Disclosures (ASC 820) , as the price that would be received upon selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 – Quoted prices in active markets for identical assets and liabilities. • Level 2 – Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The Company’s money market funds are measured using Level 1 inputs. The following table presents available-for-sale securities measured at fair value on a recurring basis as of June 30, 2019 : (in thousands) Total Fair Value Quoted Prices in Significant Other Significant Balance Sheet Assets: Money market funds $ 23,425 $ 23,425 — — Cash and cash The following table presents available-for-sale securities measured at fair value on a recurring basis as of March 31, 2019 : (in thousands) Total Fair Value Quoted Prices in Significant Other Significant Balance Sheet Assets: Money market funds $ 25,645 $ 25,645 — — Cash and cash The fair value of the money market funds approximates their carrying amounts due to the short-term nature of these financial assets.

Share Repurchases	Share Repurchases In May 2017, the Board of Directors authorized a share repurchase program whereby the Company may repurchase up to an aggregate of $2.0 million of its outstanding Class A Common Stock (the 2017 authorization). The 2017 authorization is in addition to the $0.1 million that was remaining from the August 2011 $20.0 million authorization (the 2011 authorization). There were no shares repurchased under the 2017 authorization during the three months ended June 30, 2019. During the three months ended June 30, 2018, 82,347 shares were repurchased under the 2017 authorization, at a weighted average purchase price of $2.85 per share. As of June 30, 2019 , there was approximately $0.7 million remaining for additional share repurchases under the 2017 authorization. Additionally, in the three months ended June 30, 2019 , and June 30, 2018 , the Company repurchased 80,936 and 51,210 shares of Class A Common Stock, respectively, from certain employees that were surrendered to satisfy the minimum statutory tax withholding obligations on the vesting of restricted stock, RSUs and PSUs. These repurchases were not included in the authorized share repurchase programs and had a weighted-average purchase price of $2.15 and $3.32 per share, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets Disclosure [Text Block]	Intangible Assets Intangible assets include customer relationships, trade names, developed technology and other intangibles. Intangible assets with determinable lives are amortized over their estimated useful lives. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the asset’s carrying amount over its fair value. There was no intangible asset impairment during the three months ended June 30, 2019 , or the three months ended June 30, 2018.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Condensed consolidated financial statements	The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. The Condensed Consolidated Financial Statements have been prepared using generally accepted accounting principles (GAAP) in the United States for interim financial reporting, and consistent with the instructions of Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2019 . All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and that affect revenue and expenses during the periods reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, intangible assets fair value, depreciation, income taxes, right-of-use lease assets and related lease liabilities, and contingencies, among other things. Actual results could differ from those estimates.
New Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (ASU 2016-02). In September 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842) (ASU 2017-13), which provides additional implementation guidance on ASU 2016-02. ASU 2016-02 requires lessees to recognize leases on the balance sheet as right-of-use assets, representing the right to use the underlying asset for the lease term, and a corresponding lease liability for leases with terms greater than one year. The liability will be equal to the present value of lease payments while the right-of-use asset will be based on the liability, subject to adjustment, such as prepaid lease payments. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842 (Leases) , which provides narrow amendments to clarify how to apply certain aspects of the new lease standard. In July 2018, the FASB also issued ASU 2018-11, Targeted Improvements . The amendments in this ASU provide for an additional transition method in which an entity applying the lease standard at adoption date recognizes a cumulative-effect adjustment to the opening balance of retained earnings (deficit) in the period of adoption. The Company adopted the lease standard on April 1, 2019, using the modified retrospective method. Under this method, the new guidance would apply to existing and new leases on the date of initial application while comparative prior periods would be reported in accordance with the Topic 840 guidance effective prior to April 1, 2019, and requiring no retrospective adjustments. Upon adoption, total assets and liabilities increased due to recording the right-of-use assets of $1.3 million and lease liabilities of $1.2 million . Refer to Note 2 for additional disclosures around leases. In July 2018, the FASB issued ASU 2018-09, Codification Improvements (ASU 2018-09). ASU 2018-09 does not prescribe any new accounting guidance, but instead makes minor improvements and clarifications of several different FASB Accounting Standards Codification areas based on comments and suggestions made by various stakeholders. The Company adopted ASU 2018-09 effective April 1, 2019. The amendments had no impact to the Company's Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (ASU 2018-13). This update modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. Certain disclosure requirements established in Topic 820 have been removed, some have been modified and new disclosure requirements were added. This new standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2018-13 may have on the Company’s Condensed Consolidated Financial Statements and related disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (ASU 2018-15). The main objective of ASU 2018-15 is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments in this update require that a customer in a hosting arrangement that is a service contract follow the guidance in Subtopic 350-40 to determine which implementation costs should be capitalized as an asset and which costs should be expensed and states that any capitalized implementation costs should be expensed over the term of the hosting arrangement. This new standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2018-15 may have on the Company’s Condensed Consolidated Financial Statements. In November 2018, the FASB issued ASU 2018-18 Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 (ASU 2018-18). The update provides guidance on the interaction between Revenue Recognition (Topic 606) and Collaborative Arrangements (Topic 808) by aligning the unit of account guidance between the two topics and clarifying whether certain transactions between collaborative participants should be accounted for as revenue under Topic 606. ASU 2018-18 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2018-18 may have on the Company's Condensed Consolidated Financial Statements.
Revenue [Policy Text Block]	Revenue Recognition and Deferred Revenue The Company records revenue based on a five-step model in accordance with ASC Topic 606, Revenue From Contracts With Customers (ASC 606). The Company's revenue is derived from the sale of products, software, and services identified in contracts. A contract exists when both parties have an approved agreement that creates enforceable rights and obligations, identifies performance obligations and payment terms and has commercial substance. The Company records revenue from these contracts when control of the products or services transfer to the customer. The amount of revenue to be recognized is based upon the consideration, including the impact of any variable consideration, that the Company expects to be entitled to receive in exchange for these products and services.
Inventory	Inventories are stated at the lower of first-in, first-out cost or market value.
Fair Value Measurement	Fair value is defined by ASC 820, Fair Value Measurements and Disclosures (ASC 820) , as the price that would be received upon selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value.
