GBZ Main Board

Original

A Raspberry Pi Zero is the recommended starting point.

Alternatives

Tested

A Raspberry Pi 2 or 3 are usable, but will require manually removing the USB ports, ethernet ports, GPIO headers, and possibly ripping the PCB down in size.

Raspberry Pi 2 Model B

Raspberry Pi 3 Model B

The new Raspberry Pi Zero W will also work, making WiFi and Bluetooth dongles non-necessary.

Raspberry Pi Zero W

Not Tested - Advanced

These systems are available and roughly the same size as a typical Raspberry Pi, and have been used or theorized to be usable by some of the more advanced modders.

Intel Core M vPro STK2MV64CC stick Super Expensive Very powerful Kind of large Might be 'plug & play' (or as close to such a thing for us) if you can work around it's size. No GPIO, interface via Arduino or Teensy via usb. Windows only? Project example

UPCore Atom CPU so windows or linux at your choice Oodles of I/O options Kinda big for GBZ or MintyPi project

UDOO NEO ARM Cortex-A9 Claims to support Android or Ubuntu linux Vaguely RPi2/3 form factor Has an LVDS port for driving raw screens Bunch of GPIO including SPI, I2C, etc
