Questions
How big is the LocoNet Shield PCB?
It measures 55 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LocoNet Shield use?
28 parts, built around the ARDUINO UNO R3, LM393 and 1N5819WS. 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 LocoNet Shield KiCad files?
From the acwright/Wright-Train-Works repository on GitHub, at the commit this page was made from: the board is Hardware/LocoNet Shield/LocoNet Shield.kicad_pcb and its schematic Hardware/DCC Decoder Shield/DCC Decoder Shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LocoNet Shield 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).
