Questions
How big is the NFC Hat PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NFC Hat use?
37 parts. 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 Hat KiCad files?
From the sbc-fish/NFC-Hat repository on GitHub, at the commit this page was made from: the board is nfc_hat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NFC Hat 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).
