Questions
What parts does the TrainTracker use?
64 parts, built around the ESP32-C3-WROOM-02-H4, 74HC595 and AMS1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TrainTracker KiCad files?
From the wcbq/TrainTracker repository on GitHub, at the commit this page was made from: the board is KiCad/traintracker/traintracker.kicad_pcb and its schematic KiCad/traintracker/traintracker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TrainTracker design in my own project?
Its repository states no licence, so its author keeps all rights: ask wcbq before reusing the design.
