Questions
How big is the ESP32-C3Devboard PCB?
It measures 21 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-C3Devboard use?
30 parts, built around the ESP32-C3, W25Q16JVUXIQ and TP4056. 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-C3Devboard KiCad files?
From the Sealflux/ESP32-C3Devboard repository on GitHub, at the commit this page was made from: the board is PCB/ESP32-C3Devboard.kicad_pcb and its schematic PCB/ESP32-C3Devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-C3Devboard 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).
