Pinout reference for PN532 NFC module over UART.

## Wiring (PN532 → Raspberry Pi)

```
PN532      RPi GPIO
-----      --------
VCC    →   5V (Pin 2)
GND    →   GND (Pin 6)
TXD    →   RXD (GPIO15, Pin 10)
RXD    →   TXD (GPIO14, Pin 8)
```

## Enable UART on RPi

```bash
sudo raspi-config
# Interface Options → Serial Port → No (login shell) → Yes (hardware)
sudo reboot
```

## Test with libnfc

```bash
nfc-list
nfc-poll
```
