Connect your Raspberry Pi to the LEGO® ecosystem with the Build HAT. Control up to four LEGO® Technic™ motors and sensors from the LEGO® Education SPIKE™ Portfolio, opening up endless possibilities for robotics, automation, and creative builds. Powered by the RP2040 chip (the same used in Raspberry Pi Pico), the Build HAT's clever design keeps all components on the bottom, leaving the top free for LEGO Minifigures or a mini breadboard. Key Features 4 LEGO Ports – Connect up to four Technic motors or sensors RP2040 Powered – Raspberry Pi's own microcontroller chip Clean Top Design – Components underneath, space on top 40-Pin GPIO – Compatible with all 40-pin Pi boards SPIKE Portfolio Support – Works with LEGO Education components Compatibility Raspberry Pi 4 Raspberry Pi 3 Model B/B+ Raspberry Pi Zero / Zero W / Zero 2 W Raspberry Pi 400 (with ribbon cable extension) Any 40-pin GPIO Raspberry Pi board Installation Options Direct attachment with 9mm spacers for stable fit Extra-tall header to keep GPIO pins accessible Ideal For LEGO robotics projects STEM education Creative builds combining Pi and LEGO Learning programming with physical outputs Note: LEGO motors, sensors, and Raspberry Pi sold separately. Requires 8V barrel jack power supply for motors (7.5V adapter available separately).
