Ultra-Compact 2A DC Motor Speed Controller (PWM)

1.8V to 12V DC | 30W Max | Adjustable Driver Module with Switch

This ultra-compact DC Motor Speed Controller allows you to control both the speed and direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage. Featuring a wide input voltage range and an onboard resettable safety fuse, this high-efficiency module is perfect for DIY electronics, robotics, and small fan or motor speed adjustments.

????️ Key Features

Wide Voltage Range: Operates smoothly across low-voltage applications from 1.8V up to 12V DC.

Built-in Switch Function: The integrated potentiometer knob controls the speed and features a physical "click" to turn the power completely ON/OFF.

Overcurrent Protection: Features a 2A self-recovering PTC fuse that automatically protects the module from short circuits and over-current scenarios.

High Efficiency: Low-heat design providing stable PWM regulation with minimal power loss.

Easy Installation: Equipped with a standard 4-position screw terminal block for solderless wire connections and dual mounting holes.

???? Wiring & Connection Guide

The green 4-pin screw terminal block makes connection straightforward. Looking at the terminal block (typically labeled on the bottom of the PCB):

Power + (V+ / IN+): Connect to the positive terminal of your DC power supply (1.8V−12V).

Power - (V- / IN-): Connect to the negative terminal (GND) of your DC power supply.

Motor + (M+ / OUT+): Connect to the positive lead of the DC motor.

Motor - (M- / OUT-): Connect to the negative lead of the DC motor.
