Mini 5A PWM DC Motor Speed Controller Module (3V–35V) – LED Dimmer Switch

The Mini 5A PWM DC Motor Speed Controller Module is a compact and efficient solution for controlling the speed of DC motors or adjusting the brightness of DC-powered LED lights. Using Pulse Width Modulation (PWM) technology, it enables smooth and precise control while maintaining high efficiency and low heat generation.

This module supports a wide input voltage range of 3V to 35V DC and can handle up to 5A of current with a maximum control power of 90W. The onboard potentiometer allows easy adjustment of motor speed or LED brightness, while the built-in self-recovery fuse ensures safe operation and protects the circuit from overload conditions.

Its small size and simple wiring make it ideal for DIY electronics, robotics projects, LED lighting control, and compact DC power regulation systems.
