First Impressions: Navigating the LCC Fusion Project Documentation

As the creator of the LCC Fusion Project, I set out to build not just a powerful hardware and firmware ecosystem, but also a documentation system that would make it accessible to anyone, even those completely new to electronics and automation. When I first started this project, I was new to electronics, PCBs, and programming enhancements to the existing LCC open-source projects. Through trial, research, and hands-on development, I built a framework that captures everything I learned—so that other model railroaders and DIYers looking for advanced automation can benefit from my experience.

But does it actually succeed? Let’s take a deep dive into how this documentation supports DIY users in bringing LCC automation to their projects—starting with building an LCC Node to control signaling.

Structuring the Documentation for DIY Users

From the start, I wanted to ensure that the documentation was structured and intuitive, breaking down into clear sections:

• Builder’s Bench for assembly guidance
• Setup & Configuration for firmware installation
• Quick Start Guides for essential workflows
• Planning Guides to explain best practices and advanced use cases

I also introduced Subjects & Use Cases to categorize content, making it easy to find what you need. The left-hand navigation features expandable menus, and a scroll-to-top button (represented by arrows) makes navigating lengthy pages effortless.

Designed for DIY Enthusiasts—Even Those New to Electronics

This documentation isn’t just for experienced DIYers—it’s built for those new to electronics who want to explore LCC automation without needing programming expertise. To support this, the documentation includes:

• Soldering tips for assembling PCBs
• Detailed step-by-step guides for putting everything together
• Educational content explaining how each board works
• Where and how to order components & PCBs (Gerber files provided)
• Help ordering from PCB fabricators like JLCPCB

Finding What You Need Instantly

The documentation also includes an optimized search function, allowing users to locate information without endlessly scrolling. Search results will pull up relevant guides, firmware, and assembly instructions based on keywords. Clicking on Table of Contents (ToC) links lets users jump directly to key sections, while breadcrumbs help retrace steps effortlessly.

A Visual & Interactive Learning Experience

The documentation isn’t just text-heavy—it includes diagrams, tables, videos, and printer-friendly resources to make learning engaging and effective. A Terminology section automatically links definitions to technical terms, so users don’t have to search elsewhere for explanations.

Testing the Documentation: Building an LCC Node

The real test of any documentation is how well it supports actual hands-on projects. When I followed my own guides to build an LCC Node for signaling control, the process was smooth:

• Assembly Guides walked through putting the hardware together.
• Firmware Installation was easy with step-by-step flashing instructions.
• Configuration Tools simplified setting up logic and event-based automation.
• Troubleshooting Tips quickly resolved minor issues.

Firmware Installation: No Programming Required

One of the most exciting features is the firmware installation process. The firmware documentation provides a click-to-install system where users can install firmware onto an ESP32 with a single click—no programming knowledge needed!

• Firmware variations are precompiled with different configurations.
• Users simply select the firmware they need, click install, and the ESP32 is flashed automatically via USB.
• The search feature helps users find the right firmware for their specific PCB and configuration.

Scalable Documentation for a Growing Ecosystem

This project is designed to scale. Right now, there are 50+ documented PCBs with guides for assembly, configuration, planning, and usage—and more will be added. The structured documentation system ensures that as new PCBs and firmware variations are introduced, they seamlessly integrate into the existing knowledge base.

Final Thoughts

So, did I succeed in creating documentation that actually helps users? I believe the answer is yes—but this is just the beginning. As more people build, test, and provide feedback, the documentation will continue to improve.

This project started with me learning electronics and PCB design from scratch, and now it’s a resource for others—model railroaders who want advanced automation on their layouts as DIYers. If you’re looking to explore LCC automation with clear, structured guidance, this documentation is designed to help you succeed.

And speaking of first projects—stay tuned for our next post, where we’ll put this guide to the test by designing and assembling an LCC Node PCB.
