Got a DIY project with a small DC motor, fan, or LED strip that needs speed or brightness control? This pack of 10 PWM controllers is incredibly handy. They let you smoothly adjust the speed of motors (from 1.8V up to 12V DC) or dim LEDs from 0% to 100% using a simple knob. Each module can handle a max continuous current of 2A and up to 30W of power. They have a built-in power-on LED indicator and even a switch function on the potentiometer. Importantly, they're protected by a self-resetting fuse that trips if the current gets too high, then resets once it cools down. PLEASE NOTE: These are for LOW VOLTAGE DC use only – never connect them directly to household AC power! They're perfect for tinkerers, model makers, and electronics hobbyists for controlling small motors in projects, aquarium pumps, or cooling fans. Great value in a 10-pack!
