The Libre Computer Project is an effort initiated{{when|date=February 2019}} 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. {{Cite web|url=https://forum.loverpi.com/categories/order-support|title = Order Support}} {{Cite web|url=https://forum.loverpi.com/categories/crowdfunding|title = Crowdfunding}}
Active Libre Computer SBC designs include:

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.{{cite web |title=Libre Computer |website=Twitter }} CAD files are not available.{{Cite web|url=http://forum.loverpi.com/discussion/27/libreboard-running-without-proprietary-binary-blobs|title=libreboard running without proprietary binary blobs?|website=Your Destination for Single Board Computers|language=en|access-date=2018-12-15}}
