TB6612FNG Motor Driver Breakout Board

TB6612FNG is a popular IC that can simultaneously drive two DC motors or one bipolar stepper motor.

TB6612FNG connects to a microcontroller using a popular IN1, IN2 input signal interface, choosing one of four modes such as CW (clockwise), CCW (counterclockwise), short brake and free coast mode.
