DC 12V-40V 10A PWM Motor Speed Controller, 13kHz Pulse Modulation Adjustable Switch

Need to dial in the perfect speed for your DC motor?

This little controller board lets you do just that.

It handles a wide range of input voltages from 12 all the way up to 40 volts DC and can manage a continuous current of 10 amps.

It uses a 13kHz PWM (pulse width modulation) signal to give you smooth, efficient speed control without the motor bogging down.

It's a brand new, unbranded module made in China, and it's a common go-to for DIY projects, robotics, or even adjusting the speed on small machines like drills or fans.

Just wire it up between your power source and motor, twist the knob, and you're in control.

Simple and effective.
