PWM DC Motor Speed Controller Module (5A 4.5-35V)

Need to slow down a fast fan or dim a DIY light? This module does it efficiently. Unlike simple resistors that waste power and get hot, this controller uses Pulse Width Modulation (PWM) to switch power on and off thousands of times a second. This means you get smooth speed control from 0% to 100% while maintaining good torque even at low speeds. It is equipped with a self-recovery fuse that automatically cuts power when required, protecting your motor and the board.
