Happy International Labor Holiday,Elecrow will be on holiday from May 1st to 4th.You may still place orders of products and manufacturing services as usual, and we will resume production and shipping on May 5th.
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.
