Description
Controlling the speed of DC motors, fans, or LED brightness is essential for optimizing performance, extending lifespan, and conserving energy in modern electronics. The PWM Speed Controller (DC 1.8V – 15V, 2A) is a compact and reliable module designed to help you achieve just that — using efficient Pulse Width Modulation (PWM) technology.
Whether you’re a hobbyist working on a DIY fan, a student designing a robotics project, or a professional setting up an embedded system, this module offers a low-cost and highly effective solution for precise speed control.
Let’s explore how this small controller delivers big performance.
🌟 Key Features & Benefits
⚡ PWM-Based Output for Smooth Control
Instead of wasting power like traditional resistive dimmers, this module uses Pulse Width Modulation (PWM) to efficiently control voltage supplied to the load. The result is smooth, flicker-free operation of motors and LEDs.
🔋 Wide Operating Voltage: 1.8V to 15V DC
Compatible with a broad range of power sources including battery packs, solar panels, and DC adapters. You can use it for low-voltage applications like mini-fans or LED strips without any issues.
💪 Handles Up to 2 Amps of Current
With the ability to supply up to 2A, this module is ideal for controlling small to medium loads like mini pedestal fans, model railway motors, LED panels, RC toys, and more.
🔧 Rotary Potentiometer Control (Knob)
Speed or brightness can be adjusted in real-time using the built-in rotary potentiometer. No microcontroller programming, no software—just turn the knob and control the output.
🌬️ Ideal for DC Fan Speed Regulation
This controller works perfectly for adjusting the speed of DC cooling fans used in PC cases, DIY air purifiers, small ventilation systems, or mini table fans.
💡 Can Also Act as a LED Dimmer
LED brightness can be easily dimmed by adjusting the duty cycle of PWM. Great for use in DIY mood lighting, vehicle interior mods, model lighting setups, or battery-powered LED systems.
🧠 Efficient Design Using PWM Technology
PWM allows better torque at low speeds, less heating, and increased energy efficiency. This is important for projects where battery life and thermal control matter.
🧰 Compact Size – Fits Anywhere
Small enough to fit into enclosures, custom control panels, or directly into robotic chassis or prototype boards.
🔄 Reverse Polarity Support (Recommended to Use External Diode)
Some versions of this module may offer basic reverse polarity protection, but adding an external diode is recommended for maximum safety.
