The micro:bit DRV8833 Motor Driver Expansion Board adds dual DC motor control to the BBC micro:bit. Built around the DRV8833CPWP motor driver IC, it can output up to 700 mA per channel with four control modes: clockwise rotation, anticlockwise rotation, brake, and stop.
The board includes on-board 3.3 V and 5 V voltage regulators, a serial communication interface for connecting Bluetooth modules, and 3-pin sensor interfaces for expanding your project. Motor pins A1, A2, B2, and B1 connect to micro:bit pins P13, P12, P15, and P16 respectively.

Jargon buster
Plain-language definitions for the technical terms used above.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
