Why another embedded Linux board?

Most existing boards suffer from several problems:

  • horrible mainline kernel support - vendors often provide only a terribly outdated linuxkernel
  • insufficient publicly available documentation
  • chips only sold in large quantities

We wanted a board with excellent linuxsupport, unrestricted public documentation and a CPU that can be bought at popular distributors even at quantities of a single piece.

We wanted a board everyone can use, modify and adapt for custom projects. A truly open board designed with open source software. The Gnublin2 board design was done in KiCAD. The design files are open and you're free to use them as you like.

Contrary to other boards the Gnublin2 Board isn't meant as desktop replacement. It's meant for embedded devices. There's no 3D acceleration and no HD video playback. The Gnublin2 Board is built for low-power. Power draw is about 300mW with a full-fledged Debian Linux running in idle mode. Two USB hi-speed host ports and a hi-speed device port can be used to add Wifi or hook the board up to a PC. For wired networking there's builtin 100MBit Ethernet. The Gnublin2 board also comes with two UARTs, SPI, I2C and several GPIOs at 3.3V.

For user interaction you can connect a TFT with a touchscreen. The backlight voltage generation is done by the Gnublin2.
