Hummingboard Edge/Gate GPIOs

Description

GPIO, or General-Purpose Input/Output is a mechanism that allows a computing board to provide electrical contacts for signalling to a wide range of external devices. These pins allow commerical and hobbyist projects to do things like communicate with a “breakout board”, or individual physical modules - like a motor.

Pinout Names

These are all documented in the device-tree files. By default all are GPIO pins.
