Questions
How big is the ESP32vfo PCB?
It measures 100 × 57 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32vfo use?
127 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32D, PCF8574AP and SI5351A-B-GT. 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 ESP32vfo KiCad files?
From the paulh002/ESP32vfo repository on GitHub, at the commit this page was made from: the board is Kicad/ESP32Vfo.kicad_pcb and its schematic Kicad/ESP32Vfo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32vfo 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).
