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. CAD files are not available.
