Questions
How big is the Espcnc PCB?
It measures 90 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Espcnc use?
61 parts, built around the CH340G and SS12. 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 Espcnc KiCad files?
From the m24h/espcnc repository on GitHub, at the commit this page was made from: the board is hardware/espcnc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Espcnc design in my own project?
Its repository states no licence, so its author keeps all rights: ask m24h before reusing the design.
