Raspberry Pi Build HAT for LEGO Projects
Raspberry Pi Build HAT – Control LEGO Motors and Sensors with Your Pi
The Raspberry Pi Build HAT is an add-on board that connects to the 40-pin GPIO header on your Raspberry Pi. It provides four ports for LEGO LPF2 (Powered Up) components, allowing direct control of motors, sensors, and lights from your Pi. Ideal for robotics projects, prototyping, and educational builds.

| LEGO Ports | 4x LPF2 connectors |
| Motor Support | LEGO Technic motors (medium, large, etc.) |
| Sensor Support | LEGO color, distance, and force sensors |
| Communication | UART via GPIO (serial) |
| Board Dimensions | 56.5 × 65.0 mm |
What You Can Build With This
- A LEGO rover with autonomous navigation using Pi-based code
- An interactive sorting machine using color and distance sensors
- A Raspberry Pi turtle robot with gesture controls
- An educational kit for teaching Python and robotics to students
Compatibility
This HAT is compatible with all Raspberry Pi models featuring a 40-pin GPIO header, including the Pi 4, Pi 3, and Pi Zero 2 W. It works exclusively with LEGO LPF2 components; older NXT/EV3 parts are not supported. Pair it with any Raspbian-based OS and the official Build HAT Python library.
Wiring Notes
Secure the HAT onto the GPIO header with standoffs to prevent shorts. The board requires an external 7.5–9V DC power supply (not USB) – connect via the barrel jack or screw terminals. Ensure the power plug tip is center-positive. No pull-up resistors are needed for LPF2 ports.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi 4?
Yes, the Build HAT fully works with Raspberry Pi 4 and any 40-pin model. Just ensure sufficient power for both Pi and connected components.
Do I need an external power supply?
Yes, operation requires a 7.5–9V DC power brick (center-positive). USB power from the Pi is insufficient for driving motors.
Can I control standard DC motors with this HAT?
No, it only drives LEGO LPF2 motors and sensors. For generic DC motors, consider a different motor driver HAT.
