DCC-EX is an open-source initiative designed to enhance Digital Command Control (DCC) systems for model railroading. Here’s a detailed overview of what the site offers:

Overview

DCC-EX provides resources for building and managing DCC systems, which allow model railroad enthusiasts to control multiple trains on the same track independently. This open-source project emphasizes ease of use, customization, and community support.

Key Sections

Software

• EX-CommandStation: The core software that runs on Arduino and compatible hardware to create a DCC command station.
• JMRI Integration: Information on integrating with JMRI (Java Model Railroad Interface) for advanced layout control.

Hardware

• Supported Boards: Details on compatible microcontroller boards like Arduino Uno, Mega, and STM32.
• Peripheral Modules: Guides on additional hardware such as motor shields, Wi-Fi modules, and boosters.

Documentation

• User Manuals: Comprehensive manuals for setting up and using DCC-EX systems.
• Technical References: In-depth technical details, wiring diagrams, and standards.

Community and Support

• Forums and Groups: Links to community forums, social media groups, and discussion boards.
• Tutorials and Videos: Step-by-step tutorials and instructional videos to help beginners and advanced users alike.

Getting Started

• Quick Start Guides: Simple guides to get your DCC system up and running quickly.
• FAQ: Frequently asked questions to help troubleshoot common issues.

Features

• Compatibility: Works with a wide range of DCC controllers and decoders.
• Customization: Highly customizable to fit various layout needs and preferences.
• Open Source: Community-driven with contributions from model railroad enthusiasts around the world.

Supported Ethernet modules

Arduino Network Shield 2
There have been different revisions for the Arduino Network Shields, the main difference is the version of the WiFi chip on the board. The “2” board uses the Wiznet W5500, other versions used the older W5100 chip. The only supported chip currently is the W5500, but the other boards may work as well. The W5500 can handle 8 simultaneous socket connections while the W5100 can handle 4. These boards provide a network (IP) stack capable of both TCP and UDP. This board also has an SDCard which can be used for your own custom features or for storing settings with a possible future version of EX‑CommandStation.

Wiznet WIZ850IO
This is a micro Ethernet board no bigger than the RJ45 connector it is attached to. You have to wire this with jumpers or solder it to a prototyping PCB.

Sunfounder Ethernet Shield
This board is tested and works. It is less expensive than the Arduino brand-name board and based on the Wiznet W5100 instead of the W5500. It must be the first shield in the stack because it uses the ICSP header pins.

Community Involvement

DCC-EX encourages user participation in forums and through direct contributions to the project. The community is active in developing new features, fixing bugs, and sharing best practices.
