From the project

ESP32 based LCC Boards

This is a collection of Model Railroad open hardware and open source projects, using LCC / OpenMRNIDF, for the ESP32 family of MCUs

These projects were created using Kicad 2013.06.11 (https://launchpad.net/kicad) under CentOS 6 and Kicad 4.0.7 under Ubuntu 18.04. Each subdirectory is one project, and contains a schematic and PCB design or contains a program for one (or more) projects. There is also software for the boards using OpenMRNIDF (C++ library for OpenLCB/LCC) for these projects.
