Schematics
Schematics are really straighforward, with just 4 components
- Capacitor to smooth the NFC power generation.
- Resistor to current limit the LED.
- A Yellow LED
- NFC NTAG: NT3H1101W0FHKH
The NT3H1101W0FHKH is really cool, a writable NFC tag that just needs an antenna. It will generate enough power from the NFC field to light up a LED.

Questions
How big is the Card PCB?
It measures 88.6 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Card use?
5 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 Card KiCad files?
From the diodeinc/openvcf repository on GitHub, at the commit this page was made from: the board is card/elec/layout/default/card.kicad_pcb and its schematic card/elec/layout/default/card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Card design in my own project?
Its repository states no licence, so its author keeps all rights: ask diodeinc before reusing the design.
