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.
