Questions

How big is the Base esp32 PCB?

It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Base esp32 use?

107 parts, built around the ESP32-DEVKITC-VE, DS18B20, HDS18B20 and AMS1117. 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 Base esp32 KiCad files?

From the jalmx/base_esp32 repository on GitHub, at the commit this page was made from: the board is base_esp32.kicad_pcb and its schematic base_esp32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Base esp32 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
