Questions
How big is the Nfc sense ntag panel PCB?
It measures 121 × 87.9 mm and has 4 copper layers, 0.79 mm thick.
What parts does the Nfc sense ntag panel use?
1,028 parts, built around the ATTINY1626-MF and TMP117AIDRVR. 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 sense ntag panel KiCad files?
From the unsurv/NFC_temp repository on GitHub, at the commit this page was made from: the board is hardware/nfc_sense_ntag/nfc_sense_ntag_panel.kicad_pcb and its schematic hardware/nfc_pocket_knife/pocket_knife_sense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nfc sense ntag panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask unsurv before reusing the design.
