Exhibit 23.1

Consent of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders ofSemiLEDs Corporation:

We consent to the incorporation by reference in the registration statements (No.333-171107 and 333-197417) on Form S-8 of SemiLEDs Corporation of our report dated November 29, 2017, with respect to the consolidated balance sheet of SemiLEDs Corporation and its subsidiaries as of August 31, 2017, and the related consolidated statements of operations, comprehensive loss, changes in equity and cash flows for the year then ended, and the related consolidated financial statement schedule for the year ended August 31, 2017, which reports appear in the August 31, 2017 annual report on Form 10-K of SemiLEDs Corporation. Our report dated November 29, 2017 contains an explanatory paragraph that states that the Company has suffered recurring losses from operations, has not generated sufficient net cash flows from operating activities and has an accumulated deficit, which raise substantial doubt about its ability to continue as a going concern. The consolidated financial statements and financial statement schedule do not include any adjustments that might result from the outcome of that uncertainty.
