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, this motor drive board breaks out all the interfaces with 3PIN headers, so you can easily connect other sensors to the board using 3pin wire.
At the same time, a 3.3V and 5V voltage-regulator chip is integrated on the breakout board, leading out 3.3V and 5V power output interfaces.
The board also comes with a serial communication port, easy to connect the 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


Test 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.
