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

Open Source
[edit]Software
[edit]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
[edit]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]
