README
KiCad/TRax-LaserParkDetector/README.mdPark Detector KiCad files
This is a static copy of the TRax-Schematic project at v1.7 with everythig stripped out except for the park detector. Reason being that KiCad doesn't appear to have a way to lay out a board based on only part of a schematic.
Caveat Emptor: Changes made to the main schematic will have to be replicated here. (Boo...)

Questions
How big is the TRax Controller PCB?
It measures 99.1 × 149.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TRax Controller use?
43 parts. 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 TRax Controller KiCad files?
From the vmoa/trax-pi repository on GitHub, at the commit this page was made from: the board is KiCad/TRax-Schematic/TRax-Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TRax Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask vmoa before reusing the design.
