The Raspberry Pi’s GPIO (General Purpose Input Output) allows it to talk to ‘real world things’ – other hardware and electronics – by using code to tell these things what to do and when.

You can connect dupont wires to create a circuit yourself, or attach an add-on board or HAT designed for a specific purpose.

From handy GPIO headers for your Raspberry Pi Zero 2 to full add-on boards that can control robots, stream digital TV, play music, light-up displays and more – we’ve got you covered with our huge range of GPIO add-ons.

We've also got a great selection of Raspberry Pi Pico and Pico W add-ons and headers for you to choose from too!
