Precision Control for Your DC Motors

Struggling with jerky motor movements or inefficient power delivery in your DIY projects? The Mini PWM DC Motor Speed Controller is engineered to solve exactly that. Utilizing Pulse Width Modulation (PWM) technology at a stable 10kHz frequency, this module allows you to adjust motor speed smoothly from 1% all the way to 100%. Whether you are fine-tuning a robotic arm, slowing down a noisy ventilation fan, or dimming a custom LED strip, you get absolute precision without sacrificing motor torque.

Advanced Low-Voltage Drive Technology

Don't let its miniature size fool you. Powered by the latest low-voltage drive architecture, this tiny board supports a wide input range of DC 5V to 35V and can sustain a continuous current of up to 5A. With a maximum control power of 90W, it punches far above its weight class, making it a versatile backbone for both 12V and 24V electronic applications. Furthermore, its ultra-low standby current of just 0.015A ensures your battery-powered setups remain efficient.

Smart Self-Recovering Fuse Protection

Accidental short circuits and power surges happen. Traditional controllers require you to manually desolder and replace blown fuses—but not this one. This module is equipped with a smart self-recovering fuse. If the current exceeds safe limits, the connection is instantly severed to protect your equipment. Once the power is cut and the board cools down for a few seconds, the fuse automatically resets itself. You will almost never need to replace a fuse again.

Ultra-Compact, Space-Saving Design

Space is always at a premium in custom electronics and maker projects. Measuring just 30mm x 24mm x 15mm (excluding the rotary knob), this speed controller can be easily tucked away into tight enclosures, custom 3D-printed cases, or crowded breadboard setups. The integrated rotary knob provides a satisfying, tactile feel for real-time speed adjustments.
