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.
Comes with development resources and material
Onboard standard servo headers
Onboard multi connectors.

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 DC 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.
