The Dual Channel H-Bridge Motor Shield is composed of 2 discrete MOSFET H-bridge, designed to drive two DC motor with max current 8A. It is made up of 8 N-channel MOSFET IRF3205S and 4 pcs of half bridge motor controller IR2104, to build 2 H-bridge. With this shield and the Arduino board, users can control and drive motors with a max current 8A@ 22V. The universal 7.4~11.1V lipo battery that are popular used in the remote car and model airplane can be applied as well.
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.
- Uses the IRF3205S MOSFET, which support max current up to 110A
- Uses Half bridge motor controller IR2104, to avoid H-bridge shortage.
