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.


  • 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

    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, labeled as P0, P1, and P2 to connect up to 3 servo motors and up to 2 DC motors on the connector labeled 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.
