The Grove - I2C Motor Driver (TB6612FNG) can drive two DC motors up to 12V/1.2A or drive one stepper motor up to 12V/1.2A. With the on-board MCU, it can work with Arduino easily via the Grove I2C interface.
This diver board is based on TB6612FNG, which is a driver IC for the DC motor and stepper motor with output transistor in LD MOS structure with low ON-resistor. Two input signals, IN1 and IN2, can choose one of four modes such as CW, CCW, short brake, and stop mode.
