This PWM (Pulse-Width Modulation) DC motor speed controller is an adjustable speed control module for DC motors and other DC loads within the 6 V–28 V range. It uses PWM to efficiently regulate motor speed by modifying the duty cycle of the supply voltage.

 Key Features

  • Input Voltage: DC 6–28 V – compatible with typical 12 V and 24 V DC systems.

  • PWM Frequency: ≈ 21 kHz – high-frequency PWM for smoother control and reduced noise.

  • Duty Cycle Control: 0 % to 100 % – fine adjustment from stopped to full speed.

  • Max Continuous Current: 3 A – suitable for small/medium DC motors and loads (~80 W max).

  • Direction Control: Some versions include forward/reverse control via buttons.

  • Potentiometer: Adjustable knob for intuitive speed control.

  • LED Display (optional): Shows PWM duty cycle as a numeric value (e.g., “055” for 55 %).

  • Compact Module: Easy to embed into DIY and electronic projects.

 Typical Uses

✔️ DC motor speed control in robotics, models, fans, pumps and more.
✔️ Adjustable speed applications in hobby circuits.
✔️ DIY electronics projects requiring variable DC motor control.

Note: Do not connect this module directly to AC mains voltage (e.g., 220 V AC) — it’s designed only for DC systems.
