The DC Motor Speed Controller allows controlling direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100%. The motor speed controller can provide a continuous current of 8A to your DC motor or other DC load. The circuit also includes a 10A fuse, with the reverse connection of power supply and control voltage over-voltage protection function.

Note: This can NOT be used to the BRUSHLESS motor. The controller is NOT reverse-polarity protected and will be damaged if it connects the supply voltage with the wrong polarity.


  • Control the speed of a DC motor with this controller.
  • High efficiency, high torque, low heat generating.
  • With reverse polarity protection, high current protection.
