Questions

How big is the Esp32 PCB?

It measures 35 × 17 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Esp32 use?

22 parts, built around the SPX3819M5-L-3-3 and MMSS8050-H. 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 buganini/usb-dl repository on GitHub, at the commit this page was made from: the board is esp32/esp32.kicad_pcb and its schematic esp32/esp32.kicad_sch. 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 buganini before reusing the design.
