SparkFun Motor Driver - Dual TB6612FNG (1A) Colour_Brown in that you really getThe TB6612FNG Motor Driver can control up to two DC motors at a constant current of 1. 2A (3. 2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes: CW, CCW, short brake and stop. The two motor outputs (A and B) can be separately controlled, and the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of
