Questions
How big is the ESP32-C3-Mini PCB?
It measures 29.8 × 34.3 mm and has 4 copper layers, 1 mm thick.
What parts does the ESP32-C3-Mini use?
29 parts, built around the ESP32-C3-WROOM-02-H4, AP2112K-3.3, USBLC6-2SC6 and PESD5V0S1UL. 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-Mini KiCad files?
From the JL0100/My_PCB-Design_Projects repository on GitHub, at the commit this page was made from: the board is ESP32-C3_Mini_KiCad/ESP32-C3-Mini.kicad_pcb and its schematic ESP32-C3_Mini_KiCad/BlockDiagram.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-C3-Mini 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).
