DC 1.8V 3V 5V 6V 12V 2A 1803BK PWM Motor Speed Controller Low Voltage Motor Speed Regulator Switch PWM Adjustable Drive Module

This PWM DC motor speed controller uses Pulse Width Modulation to deliver smooth speed regulation across a wide voltage range (1.8V–12V) and handles up to 2A continuous current, making it a basic but functional module for low-voltage motor projects. It lacks advanced features like reverse control or speed feedback, suiting only simple applications.
