Description

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 motor drive breakout board . The TB6612FNG chip is integrated on the 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.

The code explanation as below: 

Motor1 forward:
P13 - HIGH
P12 - LOW
Speed PWM: P1

Motor2 forward:
P15 - HIGH
P16 - LOW
Speed PWM: P2

Motor1 Backward:
P13 - LOW
P12 - HIGH
Speed PWM: P1

Motor2 Backward:
P15 - LOW
P16 - HIGH
Speed PWM: P2

Testing Result

Wiring as the above diagram, done powering up and uploading the code, two motors first turn forward for 3 seconds, then reverse for 3 seconds, circularly.
