MD30C 30Amp 5V-30V DC Motor Driver

£37.79 £31.49
The MD30C offers bi-directional control for a single brushed DC motor, making it perfect for a wide range of applications. With a motor voltage range of 5V to 30VDC and a maximum output current of 30A continuous or 80A peak (1 second), you can be confident in its power and performance.

The MD30C DC Brushed Motor Driver is a robust and user-friendly solution for powering medium to high-power brushed DC motors. It offers an impressive peak output of 80A (for 1 second) and a continuous 30A current, all while maintaining efficiency without needing additional cooling.

The MD30C is designed for ease of use. It features a full NMOS design for swift switching times and reduced energy waste. Plus, it includes reverse polarity protection for Vmotor, ensuring safety.

This motor driver is versatile, supporting both 3.3V and 5V logic level inputs, making it compatible with popular platforms like Arduino and Raspberry Pi.

Regenerative braking capability enables precise motor control, allowing you to stop the motor quickly when needed. The onboard PWM generator, complete with switches and potentiometer, simplifies control without requiring extra controllers.

Whether you're a hobbyist or engineer, the MD30C DC Brushed Motor Driver empowers you to unlock the full potential of your brushed DC motors, delivering power, efficiency, and ease of use in a compact package.
