Embed Notice

JLCPCB shipped my boards.

Already spotted one mistake, "pull-ups" instead of "pull-downs".

Anyway. This is an AVR32DD14 based board (I wanted an excuse to play with embedded Rust on 8 bit) with the following functions:

• 3.3V power supply

• Allow Linux SBC to power itself off completely

• Power on Linux SBC when button pressed

• Send shutdown signal to Linux SBC when button held

• Control LED lighting button based on a GPIO input, e.g. Linux's LED driver with heartbeat trigger

• Two extra pins broken out for future use

• I2C for configuration
