Questions
How big is the ESP32Vfo PCB?
It measures 81.9 × 57 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32Vfo use?
84 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32D, PCF8574AP and LM1117-3.3. 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/ESP32Controlerv2 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 states no licence, so its author keeps all rights: ask paulh002 before reusing the design.
