3A DC Motor Speed Controller Module

The 1203BS DC motor speed controller is a practical and reliable controller for adjusting both the speed and rotation direction of DC motors and linear actuators (electric push rods). Using PWM speed control at 21 kHz, it provides smooth and precise motor control without torque loss, delivering stable performance even at low speeds.

This PWM DC motor controller supports 6–24V DC input, making it fully compatible with 6V, 12V, and 24V motors. Speed can be adjusted from 0 to 100% using the onboard knob or switch. The built-in Forward/Reverse switch lets you change the motor’s rotation direction easily, without any extra wiring.

With an output current of up to 3A, this forward/reverse DC motor controller is suitable for small to medium DC motors, linear actuators, robotics projects, light automation, and DIY builds. The high PWM frequency also helps reduce audible motor noise and ensures smoother operation at low RPM.

Thanks to its compact size (57 × 37 × 21 mm) and lightweight design (53 g), this light-industrial motor control module is easy to install in tight spaces. Simple wiring, easy installation, and stable performance make it a great choice for educational projects, light industrial applications, and home automation.
