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.
