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 commercial and hobbyist projects to do things like communicate with a “breakout board”, or individual physical modules – like a motor. Below is the layout of the GPIOs on the HummingBoard Gate/Edge:
