The Libre Computer Project is an effort initiated{{when|date=February 2019}} by Shenzhen Libre Technology Co., Ltd., with the goal of producing standards-compliant single-board computers (SBC) and upstream software stack to power them.

Hardware

Libre Computer Project uses crowd-funding on Indiegogo and Kickstarter to market their SBC designs.

Active Libre Computer SBC designs include:

Open Source

Software

Libre Computer is focused on upstream support in open-source software using standardized API interfaces. This includes Linux, u-boot, LibreELEC RetroArch, and more. A variety of open-source operating systems may be used on Libre Computer boards, including Linux and Android. Few to no binary blobs are used to boot and operate the boards.

Hardware

Schematics and 2D silkscreen are available for all hardware. Design files are based on non-disclosure materials from SoC vendors.[19]CAD file are not available.[20]
