Arduino R3 Motor Shield for DCC-EX

Overview
The Arduino R3 Motor Shield is a powerful and versatile accessory tailored for model railway enthusiasts leveraging DCC-EX systems. Designed to pair seamlessly with the Arduino Uno R3, this motor shield transforms your board into a capable and cost-effective Digital Command Control (DCC) station. With dual motor channels and robust performance, it’s perfect for driving locomotives, controlling accessories, and automating layouts with precision.


Key Features

  • Optimized for DCC-EX: Fully compatible with DCC-EX Command Station firmware, enabling quick and reliable setup for controlling locomotives, turnouts, and other DCC accessories.
  • Dual H-Bridge Motor Drivers: Equipped with L293D ICs, it provides independent control for two motor channels, ensuring smooth and efficient operation of trains and accessories.
  • Stepper Motor Capability: Supports stepper motors for advanced turnout mechanisms or animations within your layout.
  • PWM Speed Control: Allows for fine-tuned control of locomotive speed and direction, replicating realistic train movements.
  • Stackable Design: Fits directly onto the Arduino Uno R3, leaving additional pins accessible for sensors or lights to enhance your setup.
  • Built-In Protection: Overcurrent and thermal safeguards protect both the motor shield and connected devices for safe, long-term operation.
  • External Power Support: Drive motors and accessories with an external power supply to handle higher power demands without straining the Arduino.

Why It’s Perfect for DCC-EX Users
