Giant Board – A single-board computer in the Adafruit Feather form factor


Giant Board is an Open Source, Linux-capable SBC Compatible with the Featherwing Ecosystem.

The Giant Board will come with over 100 CircuitPython libraries pre-installed and support many popular FeatherWings. Linux drivers interface directly with the Ethernet and LCD FeatherWings, and they can be easily enabled or disabled via a simple text file. Most FeatherWings will work out of the box with Adafruit’s CircuitPython example code.
