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
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]
- Rockchip RK3328 SoC
- Up to 4GB DDR4-2133 SDRAM
- 2 USB 2.0 Type A
- 1 USB 3.0 Type A
- Gigabit Ethernet
- 3.5mm TRRS AV Jack
- HDMI 2.0
- MicroUSB Power In
- MicroSD Card Slot with UHS support
- eMMC Interface with 5.x support
- IR Receiver
- U-Boot Button
- 40 Pin Low Speed Header (PWM, I2C, SPI, GPIO)
- ADC Header
- Power Enable/On Header
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]
- Amlogic S905X SoC

- H.264 1080P60
- JPEG
- Decoders
- 4 ARM Cortex-A53 @ 1.512GHz
- Up to 2GB DDR3 SDRAM
- 4 USB 2.0 Type A
- 100 Mb Fast Ethernet
- 3.5mm TRRS AV Jack
- HDMI 2.0
- MicroUSB Power In

- UART Header
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]
