WiThrottle is a protocol that works with JMRI and many command stations for basic locomotive control. DCC-EX offers native integration with advanced features like CV programming, real-time monitoring, and direct command station management - no additional software required!
JMRI (Java Model Railroad Interface) is free, open-source software that acts as a bridge between your computer and your DCC command station. When running JMRI with WiThrottle Server enabled, ThrottleCard can connect to control your trains, turnouts, and routes. JMRI supports many popular command stations including Digitrax, NCE, ESU, and others. Learn more at jmri.org.
DCC-EX is an open-source DCC command station system that runs on Arduino hardware. It's cost-effective, highly customizable, and offers native integration with ThrottleCard - no additional software needed! DCC-EX provides advanced features like CV programming, direct WiFi connectivity, and real-time monitoring. It's perfect for both beginners getting started with DCC and advanced users who want full control over their systems. Learn more here.
