RFID NFC Overview

RFID / NFC overview

Menu path: More → RFID/NFC

Hardware

• PN532 module on SPI (not I2C in default firmware).
• Arduino library: Adafruit PN532.
• Default SPI pins: PN532_SCK, PN532_MISO, PN532_MOSI, PN532_SS in shared.h — must not conflict with CC1101, SD, or touch on your wiring.

Session note

Firmware may remount SD if the reader fails to start, and can share the SPI bus between PN532 and SD for the session. Avoid hot-removing SD during an RFID session.
