Compact PWM DC Motor Speed Controller 1.8V-12V 2A with Potentiometer

This compact PWM (pulse-width modulation) controller delivers precise, smooth speed control for brushed DC motors, as well as brightness control for LED lighting and power regulation for heating elements. It operates across a wide low-voltage range of 1.8V to 12V and supports a continuous load current of up to 2A. The board features a convenient rotary potentiometer, a filtering capacitor, and reliable screw terminals, so you can connect power and load quickly and safely without soldering. Key features: Product type: miniature smooth speed control module (DC Motor PWM Controller) Specifications: operating voltage range 1.8V–12V, maximum current up to 2A, built-in potentiometer (B104), screw terminals Applications: smooth speed control for low-power DC motors, LED brightness adjustment, and heating control
