PinOne Button Board
Introduction
The button board connects to the PinOne main to expose 14 button inputs as well as allow for 16 low power 5v outputs to power LEDs on up to 5 RGB and 4 single color LED buttons, as well as an additional 5 "always on" buttons.
Compatibility
The button board is only compatible with the PinOne Main board. The PinOne Mini already has button inputs/outputs exposed on the board itself.
Models for mounting
If you would like 3d print some models for mounting brackets, one of my customers created some nice designs from them below:
