Introducing the DC Motor Speed Controller PWM 4.5V-35V 5A 90W, a must-have tool for anyone seeking precise control over their DC motors. This controller uses Pulse Width Modulation (PWM) to smoothly adjust motor speed, offering a wide operating voltage range from 4.5V to 35V. Whether you're working on DIY electronics, robotics, or industrial projects, this PWM controller allows for both speed and direction control, and even includes features like soft start and smooth stop for seamless operation. With a maximum output power of 90W, this controller is powerful enough for a variety of motor-driven applications.

One of the standout features is its user-friendly interface. The potentiometer knob allows for easy adjustment of the motor’s speed by changing the output duty cycle, giving you precise control with minimal effort. Plus, its compact size of just 30mm x 26mm x 14mm means it fits easily into tight project spaces without compromising performance. For those looking to power their projects directly from a microcontroller like Arduino, the current draw can be reduced by simply adding a resistor, or you can opt for full control using a PN2222 transistor.

Designed with versatility in mind, the DC Motor Speed Controller is perfect for applications like robotics, model engineering, and home automation. Whether you're adjusting the speed of a fan, conveyor belt, or robotic arm, this PWM controller ensures efficient power usage with minimal heat generation, making it an ideal choice for battery-powered or portable projects. Upgrade your motor control with this powerful and flexible solution today!
