Run DC Motor driver from micro:bit motor driver board

SB components organization is one of the leading brands in the market. They analyse the problems of the people about the setup of the DC motor with the micro:bit. They did their research about the problems and they came with the idea of the “motor driver for micro:bit” that became a solution for the users. Motor driver for micro:bit is an advanced driver that consists of a TB6612FNG, a powerful integrated chip, that acts as the heart of the board of motor driver. 

Powerful components of SB Motor driver

SB Components developed an extension for the Motor driver that would help the user to interface the DC motor driver for micro:bit with two DC motors and 3 PWM(Pulse Width Modulation) Servo motors simultaneously. It works on a power supply (external) of 6V~12V (VIN terminal) with the current(output) of up to 3A. SB Component’s Motor driver is compatible with both micro:bit and micro:bit v2 that would be useful for a large section of the users. Sb Components designed one of the advanced micro:bit driver expansion board to make the
