3–35V 5A PWM DC Motor Speed Controller

The 3–35V 5A PWM Motor Speed Controller is a small, efficient module for controlling the speed of brushed DC motors using pulse‑width modulation (PWM). It supports a wide input range from 3 V to 35 V and can handle up to 5 A of load current, making it suitable for motors up to about 90 W when properly cooled.

Key Features

Wide input voltage: Works from DC 3 V to 35 V, compatible with 3.3 V, 5 V, 9 V, 12 V, 24 V systems.
Up to 5 A output current: Suitable for small and medium brushed DC motors up to around 90 W.
PWM speed control: Uses pulse‑width modulation for efficient, low‑loss speed regulation.
Adjustable duty cycle: 1–100 % duty cycle range for fine control from stop to full speed.
High PWM frequency: Typical PWM frequency around 10 kHz, reducing audible motor noise.
Built‑in potentiometer: On‑board knob to start/stop and adjust motor speed.
Compact module: Small PCB (around 30 mm × 24–26 mm) convenient for integration in enclosures.
Self‑resetting fuse (many variants): Over‑current protection using an onboard resettable fuse.

Applications

DC motor speed control: Fans, blowers, pumps, small conveyor belts, and DIY motor projects.
Robotics and RC projects: Speed control for small robot drive motors and mechanisms.
LED dimming: Brightness adjustment for high‑power DC LED strips within current limits.
DIY tools and equipment: Speed control for miniature drills, stirrers, and hobby tools.
Heater power control: Power regulation for low‑voltage DC heating elements.

Connections and Usage

Connect your DC power supply to the DC IN + and DC IN − terminals within the 3–35 V range.
Connect the motor or DC load to the MOTOR + and MOTOR − terminals, observing polarity.
Turn the knob clockwise to increase the PWM duty cycle and motor speed; turn fully counter‑clockwise to stop.
Always disconnect power before changing wiring or connecting a different motor.

Important Notes

Ensure the motor’s rated voltage and current do not exceed the module’s 3–35 V and 5 A limits.
Use adequate heat sinking and wiring for high currents near 5 A to avoid overheating and voltage drop.
This controller is designed for brushed DC motors; it is not suitable for brushless motors without a dedicated driver.
Reversing motor direction requires swapping motor leads or using an external H‑bridge / polarity reversal switch.
