Cytron MD10-POT Potentiometer & Switch Control DC Motor Driver 10 Amp 7V-30V
The MD10-POT is a compact, single-channel DC motor driver designed for straightforward speed and direction control of small to medium DC motors. It accepts a wide input voltage range and integrates convenient user controls so hobbyists and developers can quickly connect a battery and motor and begin testing. The board exposes clear user-accessible terminals and indicators for power and motor status, simplifying bench work and rapid prototyping.
Control is provided through either a hand-mounted potentiometer and direction switch or via standard PWM and DIR logic inputs, allowing both manual and microcontroller-driven operation. The unit handles typical motor starting loads while incorporating internal protection behavior, and its behavior under external PWM control mirrors the supplied input, making it flexible for embedded systems as well as manual setups.
Mechanically compact and easy to wire, the MD10-POT places functional elements power, motor outputs, LEDs, and test buttons within easy reach. Its design emphasizes practical usability over complexity: set the potentiometer for open-loop speed adjustments, flip the direction switch for quick reversals, or feed PWM signals for programmatic control during development and testing. Documentation includes wiring guidance, a truth table for PWM/DIR logic and basic troubleshooting notes for users.
