Questions
How big is the Railcom reader PCB?
It measures 65.5 × 75.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Railcom reader use?
31 parts, built around the L7805 and LM339. 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 Railcom reader KiCad files?
From the dikkedimi/RailcomDetector repository on GitHub, at the commit this page was made from: the board is Kicad project/railcom reader.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Railcom reader design in my own project?
Its repository states no licence, so its author keeps all rights: ask dikkedimi before reusing the design.
