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 onboard MCU, it can work with Arduino efficiently via the Grove I2C interface.
This diver board is based on TB6612FNG, a driver IC for 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: CW, CCW, short brake, and stop mode.
