The Raspberry Pi Build HAT brings the exciting worlds of Raspberry Pi and LEGO® together for some hands-on educational fun.
The Raspberry Pi Build HAT combines the power of Raspberry Pi computing with LEGO® hands-on learning to enable a fun and creative learning experience for students, teachers and makers. It has been produced as part of a collaboration between LEGO® Education and Raspberry Pi to make it easy to control LEGO® Technic™ motors and sensors with Raspberry Pi computers to increase the impact and reach of STEAM learning.
It is supported by guided projects from the Raspberry Pi Foundation designed for secondary school students, the Raspberry Pi Build HAT delivers a unique hands-on learning experience that's accessible, engaging, and confidence-building for all students.
The Raspberry Pi Build HAT is compatible with the most recent generation of LEGO® Technic™ motors and sensors from the SPIKE™ Portfolio. The available sensors include a distance sensor, a colour sensor, and a force sensor. The angular motors come in a range of sizes and include integrated encoders that can be queried to find their position. The Build HAT also supports motors and sensors from the LEGO® MINDSTORMS® Robot Inventor kit, as well as most other LEGO® devices that use an LPF2 connector.
The Build HAT fits all Raspberry Pi computers with a 40-pin GPIO header, including — with the addition of a ribbon cable or other extension device — Raspberry Pi 400. Connected LEGO® Technic™ devices can easily be controlled in Python, alongside standard Raspberry Pi accessories such as a camera module.
This board can also be used with the LEGO® Maker Plate, available separately from LEGO® retailers, which allows the user to easily attach Raspberry Pi computers to the LEGO® building system. The LEGO® Education SPIKE™ Prime Set 45678 and SPIKE™ Prime Expansion Set 45681, available separately from LEGO® Education resellers, include a collection of useful elements supported by the Build HAT. The new, specially designed LEGO® Maker Plate is the first LEGO® element ever designed to connect to something that isn’t another piece of LEGO®.
The Raspberry Pi Build HAT power supply, available separately, is designed to power both the Build HAT and Raspberry Pi computer along with all connected LEGO® Technic™ devices.
The Build HAT has the distinction of being the second Raspberry Pi product, after Raspberry Pi Pico, to be powered by the Raspberry Pi RP2040 microcontroller.
