Raspberry Pi GPIO Multi-Function Expansion Board for PI 4B/3B/3B+

The Raspberry Pi GPIO Multi-function Expansion Board for PI 4B/3B/3B+ is a convenient GPIO breakout board designed to simplify wiring and prototyping with Raspberry Pi boards. It connects directly to the Raspberry Pi 40-pin GPIO header and provides clearly labelled access to GPIO, power and communication pins through pin headers and push-type terminal connectors. This makes it easier to connect sensors, relays, motors, LEDs and other external circuits without repeatedly wiring directly to the Raspberry Pi GPIO header.
