Re: Boxlight Corporation – Offering Pursuant to Registration Statement on Form S-3 (333-284493)

Ladies and Gentlemen:

We have represented Boxlight Corporation (the “Company”), a Nevada corporation, in connection with the issuance and sale by the Company of 1,333,333 shares (the “Shares”) of its Class A Common Stock, par value $0.0001 per share. The Securities are being issued and sold in a registered offering pursuant to the Company’s Registration Statement on Form S-3 (File. No 333-284493) (the “Registration Statement”) initially filed with the Securities and Exchange Commission (the “SEC”) on January 24, 2025 under the Securities Act of 1933, as amended (the “Securities Act”). The Shares are being sold to the purchasers named in the signature pages to the Securities Purchase Agreement dated September 23, 2025 (the “Purchase Agreement”), between the Company and such purchasers. A.G.P./Alliance Global Partners is serving as placement agent to the Company with respect to the Offering (the “Placement Agent”) pursuant to the Placement Agency Agreement between the Placement Agent and the Company dated September 23, 2025 (the “Placement Agreement”, and together with the Purchase Agreement, the “Transaction Documents”). The form of the Purchase Agreement and the Placement Agency Agreement have been filed by the Company as exhibits to its Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) today.

Subject to the assumptions, qualifications and limitations identified in this letter, we are of the opinion that the Shares have been duly authorized for issuance and, when issued and paid for as described in the Registration Statement and Transaction Documents, will be validly issued, fully paid and nonassessable.

In connection with the preparation of this letter, we have among other things reviewed: (i) the Registration Statement and Transaction Documents, including the filings incorporated by reference therein; (ii) the Notice of Effectiveness with respect to the Registration Statement filed by the SEC on February 5, 2025; (iii) copies of minutes, resolutions and consents, as applicable, of the Board of Directors and Pricing Committee of the Board of Directors of the Company related to the offering, certified by an officer of the Company; (iv) the Eleventh Amended and Restated Certificate of Incorporation of the Company, as amended, as certified by the Secretary of State of the State of Nevada on September 22, 2025; (v) the Amended and Restated Bylaws of the Company, certified by an officer of the Company; (vi) a certificate of existence with status in good standing from the Secretary of State of the State of Nevada dated September 22, 2025; (vii) copies of all certificates and other documents delivered at the closing of the offering; and (viii) such other certificates, documents and instruments we have deemed appropriate for purposes of this letter.
