1803BK 30W DC Motor PWM Speed

The 1803BK 30W DC Motor PWM Speed Controller is a compact and efficient module designed to regulate the speed of DC motors up to around 30 W using PWM (Pulse Width Modulation) control. By varying the duty cycle of the input signal, this controller lets you smoothly adjust motor speed while maintaining torque — ideal for robotics, fan speed control, conveyor systems, and battery-powered motor projects.

Designed to work with microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi (via PWM input), this controller offers reliable performance for medium-power DC motors.
