Raspberry Pi Pi® Build HAT Expansion Module Suitable for (Development Kits): Pi

The Raspberry Pi Build HAT is an add-on board developed in collaboration with LEGO Education to enable the control of LEGO Technic motors and sensors with Raspberry Pi computers.

It provides four connections for LEGO Technic motors and sensors from the LEGO Education SPIKE portfolio. Available sensors include a distance sensor, a color sensor, and a force sensor. The angle motors come in various sizes and feature built-in encoders that can be queried to determine their position. The Build HAT fits all Raspberry Pi computers with a 40-pin GPIO connector, including a Pi400 with a flat ribbon cable or other expansion devices.

LEGO Technic devices can be easily controlled in Python, as can standard Raspberry Pi accessories like a camera module. The separately available Raspberry Pi Build HAT power supply is designed to power both the Build HAT and the Raspberry Pi computer, along with all connected LEGO Technic devices.

The LEGO Education SPIKE Prime Set 45678 and the SPIKE Prime Expansion Set 45681, available separately from LEGO Education retailers, include a collection of useful elements supported by the Build HAT.
