Questions
How big is the ESP32 Dev Board PCB?
It measures 50 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 Dev Board use?
19 parts, built around the ESP32-WROOM-32U and AMS1117-3.3. 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 ESP32 Dev Board KiCad files?
From the ProZSolutions/ESP32_Dev_Board repository on GitHub, at the commit this page was made from: the board is ESP32_Dev_Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 Dev Board 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).
