Questions
How big is the ESP32 PCB?
It measures 44 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 use?
20 parts, built around the ESP32-WROOM-32, VS1053B-L and LD1117S33TR(MS). 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 KiCad files?
From the gvoigtlaender/Ka-Radio32-Module repository on GitHub, at the commit this page was made from: the board is ESP32.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask gvoigtlaender before reusing the design.
