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.
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:
The ROC-RK3328-CC "Renegade" board was funded on Indiegogo [3] and features the following specifications: [4]
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.
The "Tritium" board was funded on Kickstarter on 13 January 2018 [7] with the following specifications: [8]

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.
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]
The BeagleBoard is a low-power open-source single-board computer produced by Texas Instruments in association with Digi-Key and Newark element14. The BeagleBoard was also designed with open source software development in mind, and as a way of demonstrating the Texas Instrument's OMAP3530 system-on-a-chip. The board was developed by a small team of engineers as an educational board that could be used in colleges around the world to teach open source hardware and software capabilities. It is also sold to the public under the Creative Commons share-alike license. The board was designed using Cadence OrCAD for schematics and Cadence Allegro for PCB manufacturing; no simulation software was used.
The ODROID is a series of single-board computers and tablet computers created by Hardkernel Co., Ltd., located in South Korea. Even though the name ODROID is a portmanteau of open + Android, the hardware is not actually open source because some parts of the design are retained by the company. Many ODROID systems are capable of running not only Android, but also regular Linux distributions.
Rockchip is a Chinese fabless semiconductor company based in Fuzhou, Fujian province. Rockchip has been providing SoC products for tablets & PCs, streaming media TV boxes, AI audio & vision, IoT hardware since founded in 2001. It has offices in Shanghai, Beijing, Shenzhen, Hangzhou and Hong Kong. It designs system on a chip (SoC) products, using the ARM architecture licensed from ARM Holdings for the majority of its projects.
The PandaBoard was a low-power single-board computer development platform based on the Texas Instruments OMAP4430 system on a chip (SoC). The board has been available to the public at the subsidized price of US$174 since 27 October 2010. It is a community supported development platform.
Raspberry Pi is a series of small single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. The Raspberry Pi project originally leaned toward the promotion of teaching basic computer science in schools. The original model became more popular than anticipated, selling outside its target market for diverse uses such as robotics, home and industrial automation, and by computer and electronic hobbyists, because of its low cost, modularity, open design, and its adoption of the HDMI and USB standards.
CuBox and CuBox-i are series of small and fanless nettop-class computers manufactured by the Israeli company SolidRun Ltd. They are all cube-shaped and sized at approximately 2 × 2 × 2 inches and weigh 91 grams. CuBox was first announced in December 2011 and began shipping in January 2012, initially being marketed as a cheap open-source developer platform for embedded systems.

Like most fabless companies in the industry, the company outsources the actual manufacturing of its chips to third-party independent chip manufacturers such as TSMC. Its main target applications as of 2021 are entertainment devices such as Android TV-based devices and IPTV/OTT set-top boxes, media dongles, smart TVs and tablets. It has offices in Shanghai, Shenzhen, Beijing, Xi'an, Chengdu, Hefei, Nanjing, Qingdao, Taipei, Hong Kong, Seoul, Mumbai, London, Munich, Indianapolis, Milan, Novi Sad and Santa Clara, California.
The Rockchip RK3288 is an ARM architecture System on Chip (SoC) from Rockchip. It is the first SoC, in August 2014, that uses the 32-bit ARM Cortex-A17 processor. It is a quad-core processor with a NEON coprocessor and hardware acceleration for video and 3D graphics. It is used in a number of Chromebooks and other low-power, low-performance devices.
Creator is a family of single-board computers developed by Imagination Technologies to promote educational research and software development based on the MIPS architecture. The first board in the platform, the Creator Ci20, was released in August 2014. A second development kit called Creator Ci40 was introduced through a Kickstarter campaign in November 2015.
CHIP was a single-board computer crowdfunded by now-defunct Next Thing Co. (NTC), released as open-source hardware running open-source software. It was advertised as "the world's first $9 computer". CHIP and related products are discontinued. NTC has since gone insolvent.
Pine Store Limited, doing business as Pine64, is a Hong Kong-based organization that designs, manufactures, and sells single-board computers, notebook computers, as well as smartwatch/smartphones. Its name was inspired by the mathematical constants pi and e with a reference to 64-bit computing power.
The Gemini PDA is a personal digital assistant designed by Planet Computers in association with Martin Riddiford, who formerly worked on the Psion Series 5 in the 1990s, and crowdfunded via Indiegogo in 2017. The Gemini bucks the trend of modern smartphones in its screen being primarily used in landscape aspect, and having a keyboard, i.e. taking on the form of a subnotebook.
The PinePhone is a smartphone developed by Hong Kong-based computer manufacturer Pine64, intended to allow the user to have full control over the device. Measures to ensure this are: running mainline Linux-based mobile operating systems, assembling the phone with screws, and simplifying the disassembly for repairs and upgrades. LTE, GPS, Wi-Fi, Bluetooth and both cameras can be physically switched off. The PinePhone ships with the Manjaro Linux operating system using the Plasma Mobile graphic interface, although other distributions can be installed by users.
