Questions

What parts does the NFC CC use?

5 parts, built around the NT3H1101W0FHKH. 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 NFC CC KiCad files?

From the 463N7/NFC_Challenge_Coin repository on GitHub, at the commit this page was made from: the board is NFC_CC/NFC_CC.kicad_pcb and its schematic NFC_CC/NFC_CC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the NFC CC design in my own project?

Its repository states no licence, so its author keeps all rights: ask 463N7 before reusing the design.
