Short Product Description

Take precise control of your electronics with our ultra-compact 5-35V 5A Mini DC Motor Speed Controller. Designed with the latest low-voltage drive technology, this PWM regulator effortlessly handles up to 90W of power within a tiny footprint. It features a built-in self-recovering fuse that automatically protects your circuits from overcurrent—saving you the hassle of ever replacing a blown fuse. Perfect for DIY robotics, cooling fans, and LED dimming, this module delivers smooth, flicker-free adjustments from 1% to 100%.

Key Features

  • Wide Voltage Compatibility: Operates seamlessly across a DC 5V to 35V range, perfect for 12V and 24V systems.
  • High Power Output: Delivers up to 5A of current and handles a maximum power load of 90W.
  • Self-Recovering Fuse: Automatically disconnects during overcurrent and resets after cooling, eliminating maintenance downtime.
  • Smooth PWM Regulation: Offers a 1% to 100% duty cycle at 10kHz for flicker-free LED dimming and stall-free motor control.
  • Ultra-Low Standby Power: Draws only 0.015A in standby mode, preserving battery life in portable projects.
  • Miniature Footprint: Ultra-compact 30x24mm board size easily fits into the tightest project enclosures.

Full Product Description

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.

FAQ Section

  • Can this module reverse the direction of my DC motor?No, this specific module is designed solely for speed regulation (PWM control). It does not have an H-bridge or a reverse switch built-in, so the motor will only spin in one direction.
  • How exactly does the self-recovering fuse work?If your circuit experiences an overcurrent situation (exceeding the safe limit), the fuse will heat up and automatically break the circuit to protect your components. Simply disconnect the power, wait a few seconds for the fuse to cool down, and it will automatically reset itself.
  • Is this controller suitable for dimming LED lights?Yes! Because it uses Pulse Width Modulation (PWM) at a high frequency of 10kHz, it is excellent for adjusting the brightness of DC-powered LED strips smoothly and without visible flickering.

Target Users / Applications

  • DIY Electronics Hobbyists: Perfect for custom robotics, RC vehicles, and Arduino-based projects.
  • PC & Server Modders: Ideal for manually controlling the speed of 12V DC cooling fans to reduce noise.
  • Lighting Enthusiasts: Great for creating custom, flicker-free dimming switches for 12V/24V LED lighting setups.
