Ladies and Gentlemen:

We have acted as counsel to Inseego Corp., a Delaware corporation (the “Company”), in connection with the issuance and sale by the Company of up to $115,000,000 aggregate principal amount of the Company’s 3.25% Convertible Senior Notes due 2025 (the “Notes”), which includes up to $15,000,000 aggregate principal amount of the Notes that may be issued and sold pursuant to the exercise of an over-allotment option, pursuant to an Underwriting Agreement, dated May 7, 2020 (the “Underwriting Agreement”), by and between the Company and Stifel, Nicolaus & Company, Incorporated (the “Underwriter”).

The Notes are registered pursuant to a Registration Statement on Form S-3 (File No. 333-238057) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”).

The Notes will be issued pursuant to the Indenture, dated May 12, 2020 (the “Base Indenture”), by and between the Company and Wilmington Trust, National Association (the “Trustee”), as supplemented by the First Supplemental Indenture, dated May 12, 2020, by and between the Company and the Trustee (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). Pursuant to the terms of the Indenture and the Notes, up to 10,941,960 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”), may initially be issuable upon conversion of the Notes.

Based upon the foregoing, and in reliance thereon, and subject to the limitations, qualifications, assumptions and exceptions set forth herein, we are of the following opinions:

1. The issuance of the Notes has been duly authorized by all necessary corporate action on the part of the Company and, when executed, authenticated and issued in accordance with the provisions of the Indenture and delivered to the Underwriter in exchange for the consideration provided for in the Underwriting Agreement, the Notes will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

2. The issuance of the Shares upon conversion of the Notes has been duly authorized by all necessary corporate action on the part of the Company, and, assuming the conditions for conversion have been satisfied, upon issuance and delivery upon the conversion of the Notes in the manner contemplated by the Notes, the Indenture and the Resolutions, the Shares will be validly issued, fully paid and nonassessable.

The opinions expressed herein are subject to the following exceptions, qualifications and limitations:

A. They are limited by the effect of (i) any applicable bankruptcy, insolvency, reorganization, moratorium or similar law and principles affecting creditors’ rights generally, including without limitation fraudulent transfer or fraudulent conveyance laws and (ii) general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing) and the availability of equitable remedies (including, without limitation, specific performance and equitable relief), regardless of whether considered in a proceeding in equity or at law. In addition, we express no opinion as to the validity, binding effect or enforceability of any provision of the Indenture relating to the separability of provisions of the Indenture.

B. No opinion is expressed herein with respect to the validity, binding effect or enforceability of any provision of the Indenture or the Notes insofar as it purports to effect a choice of governing law or choice of forum for the adjudication of disputes or with respect to the acceptance by a federal court located in the State of New York of jurisdiction of a dispute arising under the Indenture or the Notes, other than (a) the enforceability by a New York State court under New York General Obligations Law Section 5-1401 of the choice of New York State law as the governing law of the Indenture or the Notes (subject, however, to the extent limited by the Constitution of the United States and by Section 1-301 of the New York Uniform Commercial Code), and

(b) the enforceability by a New York State court under New York General Obligations Law Section 5-1402 of New York State courts as a non-exclusive forum for the adjudication of disputes with respect to the Indenture or the Notes.

C. No opinion is expressed herein with respect to the validity, legally binding effect or enforceability of any provision in the Indenture or Notes that requires or relates to adjustments to the conversion rate at a rate or in an amount that a court would determine in the circumstances under applicable law to be commercially unreasonable or a penalty or forfeiture.

Without limiting any of the other limitations, exceptions, assumptions and qualifications stated elsewhere herein, we express no opinion with regard to the applicability or effect of the laws of any jurisdiction other than with respect to the Shares, the General Corporation Law of the State of Delaware and, with respect to the Notes and the Indenture, the internal laws of the State of New York, in each case as in effect on the date hereof.

This opinion letter is rendered solely in connection with the offering of the Notes. This opinion letter is rendered as of the date hereof, and we assume no obligation to advise you or any other person with regard to any change after the date hereof in the circumstances or the law that may bear on the matters set forth herein even if the change may affect the legal analysis or a legal conclusion or other matters in this opinion letter.
