The Libre Computer Project is an effort initiated^[when?] 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. The delivery and after-sales support was poor resulting in lots of complaints and dissatisfied funders. ^{[1] [2]}

Active Libre Computer SBC designs include:

Software[]

Operating systems[]

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.^[21] CAD files are not available.^[22]
