📝 Product Description

Control the speed of your DC motor with the 5A PWM DC Motor Speed Controller Module. Designed for low-voltage electronics projects, this compact module uses pulse-width modulation (PWM) to adjust motor speed efficiently.

The built-in rotary potentiometer makes it easy to increase or decrease motor speed according to your project requirements. With a supported input range of 3V–35V DC and a maximum rated output current of 5A, this module is a useful choice for hobbyists, students, makers, and electronics enthusiasts.

Its compact size makes it suitable for robotics, RC vehicles, small automation projects, and other DIY applications requiring adjustable DC motor speed.

Important: This is a DC motor speed controller, not a standalone power supply. The power source must match your motor's voltage and current requirements.

📋 Technical Specifications

🔧 Applications

• DIY DC motor speed control projects

• Arduino and microcontroller-based robotics

• RC cars, boats, and other hobby vehicles

• Small DC motor experiments

• Educational electronics and science projects

• DIY automation and mechanical prototypes

⚠️ Precautions

• Use DC power only. Never connect the module directly to 220V AC mains.

• Observe the correct positive and negative input polarity.

• Check the motor's rated voltage and current before connecting it.

• The 5A rating is a maximum, not a guarantee of continuous operation under every condition.

• Provide adequate cooling when operating at higher currents.

• Disconnect the power before changing wiring connections.

• This module controls speed; it does not independently provide reverse-direction control. Reverse motor direction by changing the motor connections or using a suitable motor driver.
