Motor Driver for Micro:Bit
Motor Driver for micro:bit is introduced as the latest edition of a range of SB Components that can interface with up to 2 DC motors and 3 pwm based Servo motors. It works on Motor Power supply: 6V~12V (VIN terminal) an output current of up to 3A with a powerful integrated TB6612FNG Module IC that scales up the performance. VIN terminal can be used for providing the power to the Motor driver for micro:bit.
Features
Connect up to 2 DC motor and 3 servo motor simultaneously.
TB6612FNG Motor driver IC.

Programming
Drag and Drop
Many people want to learn the process to learn more about micro:bit by getting an understanding of the potential of micro:bit. If one wants to run servo motor and C motor with the micro:bit motor driver then they can do the following steps.
A user needs to connect the PWM servo motor to the connector(3 pin header) of the servo driver board, labelled as P0, P1, and P2 to connect up to 3 servo motors and Upto 2 DC motors on connector labelled as MA1, MA2 for motor 1 and MB1 and MB2 for motor 2.
Take micro:bit and stack it on the motor driver board’s edge connector.
Connect VIN and ground or the external power supply to the motor driver to provide power to it.
A user needs to switch on the slider switch of the motor driver.
