Introduction
Micro bit is an entry level development board designed by BBC for teens programming education.
It supports the PXT graphical programming interface developed by Microsoft, and can be used under Windows, MacOS, IOS,
Android and many other operating systems without downloading the additional compiler.
In order to facilitate the micro bit to drive DC motor, we specially develop this breakout board.
Its per channel can output up to 1.2 A continuous drive current, with peak current up to 2A / 3.2A.
There are 4 motor control modes: Forward / Reverse / Brake / Stop. And PWM supporting frequency is up to 100 kHz.
For wiring, the board breaks out all the pins with the 3PIN interface, so you can connect other sensors to the board using 3pin wire.
At the same time, a 3.3V and 5V voltage-regulated chip is integrated on the breakout board, where leads to a 3.3V and 5V power output interface.
The board also comes with a serial communication port to facilitate the connection of Bluetooth module.

Details display, wiring diagram and test code are offered on keyestudio wiki page.
