Questions

What parts does the ESP32 DEV use?

45 parts, built around the ESP32-S3-WROOM-1-N8, TCAN332D, TPD4S012DRYR-TP and PESD1CAN. 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 KiCad files?

From the CalSol/calsol-hw-libs repository on GitHub, at the commit this page was made from: the board is ESP32 Template/ESP32 DEV/ESP32 DEV.kicad_pcb and its schematic ESP32 Template/ESP32 DEV/ESP32 DEV with LTC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ESP32 DEV design in my own project?

Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
