Questions
How big is the Esp32c3 devboard PCB?
It measures 47 × 34 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32c3 devboard use?
72 parts, built around the CP2102N-A01-GQFN28R, AMS1117-3.3, SRV05-4 and SK6805E-J. 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 Esp32c3 devboard KiCad files?
From the tmilkovic51/esp32c3_devboard repository on GitHub, at the commit this page was made from: the board is esp32c3_devboard.kicad_pcb and its schematic esp32c3_devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32c3 devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask tmilkovic51 before reusing the design.
