Questions
How big is the XIAO ESP32 C6 PCB?
It measures 21 × 17.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the XIAO ESP32 C6 use?
83 parts, built around the ESP32-C6FH4, FM8625H, SGM6029CYG/TR and SGM40567-4.2XG/TR. 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 XIAO ESP32 C6 KiCad files?
From the MitkoDyakov/Calipatron repository on GitHub, at the commit this page was made from: the board is Hardware/V2/Res/XIAO/XIAO ESP32 C6.kicad_pcb and its schematic Hardware/V2/Hardware V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the XIAO ESP32 C6 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).
