H-Bridge Motor Shield


This H-Bridge Motor Shield based on 8 N-channel MOSFET IRF3205S and 4 pcs half-bridge motor controller IR2104, to build 2 H-bridge. With this shield, you can control two DC motors with a max current up to 8A with 22v voltage at the same time. Also, you can control the motor direction by the logic 0 or 1 with the digital pin and speed by the PWM PIN of your MCU, like Arduino. And we support the Screw interface, it is easy to connect to the motor and power.




  • Operating Voltage: 6 - 22V
  • Continuous output current: up to 8 Amps
  • Peak output current: 15 Amps
  • PWM Duty: 0~99%

Interface Function


Attaching Antennas: Refer to the picture, combine the module with Arduino according to the pins.

Load Demo

Motor Test

Load the "Demo code" to Arduino or Maduino.

Connect the Motor to the port, and power it on. The motor will rotate a while, and then it will reverse.
