![Dual Channel H-Bridge Motor Shield (8A 22V) Dual Channel H-Bridge Motor Shield (8A 22V)](https://robolabor.ee/1029-large_default/dual-channel-h-bridge-motor-shield-8a-22v.jpg)
The H-Bridge Motor Shield can be controlled by simply applying logic 0 or 1 to the direction pins for that motor and a PWM signal to the speed pin. In this way, speed and direction of two separate motors can be controlled independently. Note that the PWM signal on the P_1 and P_2 can be 0~99%, but 100% high signal (logic 1) not works because of the motor controller IR2104 boost circuit.
Besides, the H-bridge motor shield PCB has a copper thickness of 2 oz, which make it supports larger current flow and stable. It would be your best choice creating your applications that needs large driver current for your DC motor.
