The HW-687 Mini DC Motor Speed Controller is a compact PWM-based driver that allows smooth and precise control of DC motor speed. Operating from DC 3V–35V with a 5A maximum current, it’s ideal for DIY electronics, robotics, and Arduino-based projects, offering efficient motor control in a small form factor.

HW-687 5A Mini DC Motor PWM Speed Controller

The HW-687 5A Mini DC Motor PWM Speed Controller is an ultra-compact and powerful solution for precisely controlling the speed of DC motors in a variety of DIY and professional applications. Designed to work with DC power supplies from 3V to 35V, this controller delivers up to 5A of continuous current, using pulse width modulation (PWM) to ensure energy efficiency without compromising motor performance.

This tiny yet powerful board is widely used in robotics, Arduino-based automation, RC car projects, and even small conveyor systems. With an easy-to-use potentiometer knob, users can manually adjust motor speed in real time with smooth acceleration and deceleration. The board’s small size makes it ideal for embedded installations where space is limited.

The HW-687 is perfect for integration into Arduino-based systems and other microcontroller projects. For more options, check our Electronics Components and Tools and Accessories categories.
