Hardware Example 03 — SPI NFC/RFID
Physically proven PN532 software-SPI polling, UID reading and presentation de-duplication.
PHYSICALLY PROVEN / CLOSED
| Signal | Pin |
|---|---|
| MOSI | GPIO28 |
| MISO | GPIO29 |
| SCK | GPIO30 |
| CS | GPIO31 |
| Reset | GPIO2 |
| IRQ | Unused |
Accepted PN532 proof
- —PN532 identity and software-SPI transport
- —SAMConfig and ISO14443A polling
- —Real tag detection and UID 04:8D:E6:5F:B7:2A:81
- —Card removal and re-presentation
- —One logical read per presentation through de-duplication
