particle-gen3-header

Vendor: Generic or vendor-independent

Description

GPIO pins exposed on Particle Gen3 (Feather) headers.

The Particle Gen3 boards are compatible with the Adafruit Feather
"shields" but use a different orientation and pin numbering scheme.

With the board oriented with the micro USB at the top:
* A 12-pin header on the right.  9 pins on this header are exposed
  by this binding
* A 16-pin header.  13 pins on this header are exposed by this
  binding.

This binding provides a nexus mapping for 22 pins where parent pins
0 through 8 correspond to the pins on the 12-pin header, starting
from the bottom; and pins 9 through 21 correspond to pins on the
16-pin header, skipping the bottom pin then assigning 9 through 19,
skipping over GND, and replacing the lower 3V3 with pin 20.  The
physical layout is depicted below.
