Questions
How big is the Civ2bcd PCB?
It measures 70 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Civ2bcd use?
50 parts, built around the CH32V003F4P6 and LL4148. 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 Civ2bcd KiCad files?
From the ra0sms/civ2bcd repository on GitHub, at the commit this page was made from: the board is KiCad/civ2bcd/civ2bcd.kicad_pcb and its schematic KiCad/civ2bcd/civ2bcd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Civ2bcd 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).
