If there’s a lot of people interested, there’s a chance that I’ll try to sell this at a relatively low price :P

Features

• H3 Quad-Core ARM Cortex-A7 @ 1.296GHz CPU
  • Mali400 MP2 OpenGL ES 2.0 GPU
• 512MiB of DDR3 RAM, stable at 696MHz (Upgradable to 1GiB)
• Ethernet PHY, WiFi & Bluetooth
• GPDI video out
• USB connectors:
  • 2x USB-A
  • 2x USB-C (One OTG port)
  • 1x USB-C 100W PD power port
• 3.5mm audio jack
• uSD card slot
• eMMC 5.1 storage

System support

The single-board computer is capable of running Linux (debian) and Android (H3Droid). It can output 4k video via it’s GPDI-A connector, output a tty consol via UART, or act as an remote host via ssh.

It’s small, compact form factor allows it to be a nice portable computer that you can take anywhere! It supports GPU acceleration and 4k video decoding, letting you view anything in full confort.

PCB

Check out the online version here.

The PCB is only 4 layered, ensuring minimal cost and overhead during production. But for mass production 6 layers is recommended, putting solid ground on In.1 and In.4, then copy the power plane to In.2 and In.3. (Impedance matching might be required depending on stackup)

The current setup uses JLCPCB’s JLC04161H-3313 stackup, and the BOM is optimized for use there. Using other fabs would require re-tuning the DDR3, USB and GPDI traces.

Open source

This project is licensed under the Solderpad hardware license, granting the maximum amount of liberty :)

It is also OSHWA certified under the identifier FR000029.
