Libre Computer

Libre Computer (Libre Computer Project) designs low-cost boards with Amlogic, Allwinner and Rockchip SoCs. Most of them follow the Raspberry Pi 3 footprints (CC and AC form factors) or the CM4 module format. The company maintains its boards in upstream Linux and U-Boot, ships UEFI firmware on the newer ones, and promises software support for 30 years from each board’s launch.
