The Libre Computer Project is an effort initiated 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:

ROC-RK3328-CC (Renegade)

The ROC-RK3328-CC "Renegade" board was funded on Indiegogo[3] and features the following specifications:[4]

AML-S905X-CC (Le Potato)

The AML-S905X-CC "Le Potato" board was funded on Kickstarter on 24 July 2017[5] and features the following specifications:[6]

NOTE: GPIO Header Pin 11 or HDMI CEC is selectable by onboard jumper. They can not be used at the same time since they share the same pad.

ALL-H3-CC (Tritium)

The "Tritium" board was funded on Kickstarter on 13 January 2018[7] with the following specifications:[8]

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]
