Questions
How big is the ESP32-Dev Kit PCB?
It measures 30.9 × 56.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32-Dev Kit use?
34 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32D, AMS1117-3.3 and MMSS8050-H-TP. 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-Dev Kit KiCad files?
From the Jazildebug/ESP32-Dev-Kit repository on GitHub, at the commit this page was made from: the board is ESP32-DEV-KIT-FINAL/ESP32 DevKit.kicad_pcb and its schematic ESP32-DEV-KIT-FINAL/ESP32 DevKit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-Dev Kit design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jazildebug before reusing the design.
