Questions
How big is the Esp32-devboard PCB?
It measures 40.4 × 36.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32-devboard use?
50 parts, built around the ESP32-C6-MINI-1U-H4, AMS1117-3.3 and 1N5819HW-7-F-01. 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-devboard KiCad files?
From the Rav4s/esp32-devboard repository on GitHub, at the commit this page was made from: the board is esp32-devboard.kicad_pcb and its schematic Buttons.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-devboard 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).
