Questions
How big is the Esp32 PCB?
It measures 151.1 × 100.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32 use?
40 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32, ESD05V88D-LC and S8050. 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 Esp32 KiCad files?
From the sourabhmisal/esp32 repository on GitHub, at the commit this page was made from: the board is esp32/esp32.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
