Versioning
First projects uses a folder per version system, easy to follow, easy to view older versions, but mess the file system.
Current system based on tags, and the creation of doc directories with PDFs of the schematic and the layers.

Questions
How big is the ArduinoDCC++ PCB?
It measures 100 × 88 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ArduinoDCC++ use?
79 parts, built around the ATMEGA328PB-AU, LMV358, FT231XS-R and L298P. 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 ArduinoDCC++ KiCad files?
From the danielvilas/DigitalTrains repository on GitHub, at the commit this page was made from: the board is ArduinoDCC++/0.0.1/ArduinoDCC++.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ArduinoDCC++ design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
