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.
This PWM DC Motor Speed Controller (12V–40V, 10A) is designed to control motor speed smoothly and efficiently using Pulse Width Modulation (PWM) technology. It supports input voltages from 12V to 40V and outputs up to 10A current, making it perfect for DC motor control, DIY automation, fans, and smart electronics projects.
