Introduction

The dual channel H-bridge motor shield is consist of 2 discrete MOSFET H-bridge, designed to drive two DC motor with the max current of 8A, whole of the dual channel H-bridge motor shield is made up of 4 half bridge motor controller(IR2104) and 8 N-channel MOSFET(IRF3205S). Connect the shield to Arduino board or bread board, you can control the motors with the max current of 8A and the max voltage of 22V.

With the help of the dual channel H-bridge motor shield, you can drive the motor with logic high and logic low, so, it’s safe to control highly current and highly voltage, apply the logical signal to the motor’s direct pin and the PWM signal to the speed pin you can control the direct and the speed of motor.
