We’re already working on more Build HAT project guides for learners. Then explore the topics of computer vision and machine learning by building an expressive robot face, and look at new ways of representing local and online data by creating a plotter or data dashboard. Whichever method you choose, make sure you position the Build HAT the right way round when installing it on your Raspberry Pi! 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. 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. With the addition of a ribbon cable or other extension device, you can also use it with Raspberry Pi 400. The new HAT works with all 40-pin GPIO Raspberry Pi boards, including Raspberry Pi 4 and Raspberry Pi Zero.

It connects to the 40-pin GPIO header and can be used to control up to four LEGO® Technic™ motors and sensors from the LEGO® Education SPIKE™ Portfolio. The Build HAT (Hardware Attached on Top), priced at $25, is a new add-on board for your Raspberry Pi.
