Questions
How big is the Rcmainboard PCB?
It measures 189.2 × 72.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rcmainboard use?
84 parts, built around the MCP4921-E/P, L7805, L7809 and LE33CZ-TR. 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 Rcmainboard KiCad files?
From the jsyk/Talking_Clock repository on GitHub, at the commit this page was made from: the board is rcmainboard/rcmainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rcmainboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask jsyk before reusing the design.
