Questions
How big is the Esp32c3 PCB?
It measures 38.4 × 27.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32c3 use?
31 parts, built around the ESP32-C3-WROOM-02-H4, AHT10, LIS2DH and A1501WR-S-2P. 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 KiCad files?
From the minddot/hw repository on GitHub, at the commit this page was made from: the board is esp32c3/esp32c3.kicad_pcb and its schematic esp32c3/esp32c3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32c3 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).
