== Description  ==
[http://microbit.org/ The BBC micro:bit ] is a powerful handheld, fully programmable, computer designed by the BBC. It was designed to encourage children to get actively involved in technical activities, like coding and electronics. <br>
It features a 5x5 LED Matrix, two integrated push buttons, a compass, Accelerometer, and Bluetooth. <br>
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.<br>

Looking to do more with your BBC micro:bit? Unlock its potential with this motor drive breakout board for the BBC micro:bit! <br>
The motor drive breakout board integrates TB6612FNG chip. Its per channel can output up to 1.2 A continuous drive current, with peak current up to 2A/3.2A.  <br>
There are 4 motor control modes: Forward/Reverse /Brake /Stop. And PWM supporting frequency is up to 100 kHz. <br>

The BBC micro:bit pins are broken out to 3PIN headers. These provide an easy way of connecting circuits using 3PIN jumper wires.<br>
At the same time, a 3.3V and 5V voltage-regulator chip is integrated on the breakout board, breaking out 3.3V and 5V power output interfaces. <br>
The board also comes with serial port communication pins.<br>

<span style=color:red>Note: <big>'''we adopt V1.5 micro:bit in the whole tutorial, but our tutorial is also compatible with the latest version micro:bit. 
When doing experiment with latest micro:bit, you need to transfer code into Makecode online editor first, save code again then download it to micro:bit.'''</big></span>

== Wiring Diagram ==
Here show you the wiring diagram below, connect the microbit and motor to our motor drive breakout board, you can observe the motor rotation.<br>
Connect the two motors to terminal block A1,A2,B1,B2;  GND to battery negative end, VM terminal to battery positive end. <br>

<span style=color:red> <big>'''The code explanation as below:'''</big> </span><br>
<pre>
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
</pre>

<br>

== 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.<br>

<br>
== Go Further == 
You can use the motor drive breakout board to control the 1-digit LED segment display. Design the circuit with your micro:bit main board and breadboard and more.  <br>
