Questions
How big is the RC-1 PCB?
It measures 42 × 30 mm and has 4 copper layers, 0.8 mm thick.
What parts does the RC-1 use?
46 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 RC-1 KiCad files?
From the OpenRTX/RC-1 repository on GitHub, at the commit this page was made from: the board is RC-1.kicad_pcb and its schematic DAC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RC-1 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
