Questions
How big is the ESP32C6 Board PCB?
It measures 100 × 50 mm and has 4 copper layers, 1.58 mm thick.
What parts does the ESP32C6 Board use?
76 parts, built around the ESP32-C6, SN74LVC1G07DBVR, USBLC6-2SC6 and ABS07-32.768KHZ-T. 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 ESP32C6 Board KiCad files?
From the phancak/ESP32C6_Board repository on GitHub, at the commit this page was made from: the board is ESP32C6_Board.kicad_pcb and its schematic ESP32-C6.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32C6 Board 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).
