The Raspberry Pi Build HAT fits any Raspberry Pi with a 40-pin GPIO header and lets you control up to four LEGO® Technic™ motors and sensors from the LEGO® Education SPIKE™ Portfolio, a flexible system with unlimited possibilities.

The new HAT works with all 40-pin GPIO Raspberry Pi boards, including Raspberry Pi 4 and Raspberry Pi Zero. With the addition of a ribbon cable or other extension device, you can also use it with Raspberry Pi 400.

The cool design of the Build HAT means that all the components are on the bottom, leaving room on the top of the board for LEGO Minifigures to hitch a ride, or for a mini breadboard. You can connect the HAT directly to your Raspberry Pi with the attached header, using 9mm spacers to ensure a stable fit, or you can add an extra-tall header to keep the unused GPIO pins accessible. Whichever method you choose, make sure you position the Build HAT the right way round when installing it on your Raspberry Pi!

Like Raspberry Pi Pico, the Raspberry Pi Build HAT uses the RP2040 chip developed right here at Raspberry Pi.
