At the most basic level, GPIO refers to a set of pins on your computer’s mainboard or add-on card. These pins can send or receive electrical signals, but they aren’t designed for any specific purpose. This is why they’re called “general-purpose” IO. This is unlike common port standards such as USB or DVI. With … See more The most common use for GPIO is to operate custom electronics.
