Questions
How big is the ESP32 Boardv2.0 PCB?
It measures 28.5 × 53.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 Boardv2.0 use?
37 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32, AMS1117-3.3 and LESD5D5.0CT1G. 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 Boardv2.0 KiCad files?
From the jminjares4/ESP32-Development-Board repository on GitHub, at the commit this page was made from: the board is ESP32_Boardv2.0.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 Boardv2.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jminjares4 before reusing the design.
