Questions
How big is the ESP32-C3 breakout PCB?
It measures 45.7 × 21.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-C3 breakout use?
32 parts, built around the ESP32-C3, BAT120C and USB4105-GF-A. 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-C3 breakout KiCad files?
From the TadeasFrycak/esp32-c3 repository on GitHub, at the commit this page was made from: the board is ESP32-C3_breakout.kicad_pcb and its schematic ESP32-C3_breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-C3 breakout design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
