BrickPi3 bridges your LEGO NXT & EV3 hardware to the Raspberry Pi — unlocking Python, C, Wi-Fi, and the full power of modern computing.
BrickPi3 replaces the MINDSTORMS Brick with the full power of the Raspberry Pi — web connectivity, multiple programming languages, and an open ecosystem, all in one elegant board.
LEGO MINDSTORMS is a powerful robotics platform, but when it comes to a networked world it has limitations. BrickPi3 was built to fix that. Plug your existing NXT or EV3 sensors and motors directly into the BrickPi3, mount it on your Raspberry Pi, and you instantly gain:
Connect up to 4 NXT or EV3 motors simultaneously. Full PWM speed control via TB6612FNG drivers rated at 1.2 A continuous.
Use any NXT or EV3 sensor — digital or analog — in any of the four sensor ports. Gyroscopes, ultrasonic, color, touch, and more.
The Raspberry Pi 3's on-board Wi-Fi lets you control your robot remotely, integrate web services, and network multiple robots together.
Official Python and C drivers are included out of the box. All source code is open on GitHub for you to tinker and extend.
12 V nominal battery powers both BrickPi3 and Raspberry Pi. Auto motor-disable protects the Pi if voltage drops below 6 V.
One Grove I²C port (5 V) with built-in level-shifting lets you attach Dexter sensors like the PivotPi servo controller.
Six-sided acrylic case with LEGO-compatible connection points on every face so you can build any robot chassis you imagine.
BrickPi3 and Raspberry Pi communicate over SPI at up to 500 kbps. Fast, reliable, and deterministic sensor & motor updates.
The Raspberry Pi sends orders over SPI to the BrickPi3 microcontroller, which drives your motors and reads your sensors — then reports back, closing the control loop.
The BrickPi3 Core is perfect if you already own a Raspberry Pi and LEGO MINDSTORMS — everything you need to get started, nothing you don't.

BrickPi3 ships with official Python and C drivers, giving you two powerful options — from quick scripting to low-level hardware control.
# Install BrickPi3 library, then:
import brickpi3
BP = brickpi3.BrickPi3()
# Set motor A to 40% power
BP.set_motor_power(BP.PORT_A, 40)
# Read a touch sensor on port 1
BP.set_sensor_type(BP.PORT_1, BP.SENSOR_TYPE.EV3_TOUCH)
value = BP.get_sensor(BP.PORT_1)
print("Touch sensor:", value)All source code and examples are available free on GitHub.
