PN532 NFC RFID Module (aka. NFC MODULE V3), Datenblatt

Der Chip lässt sich nicht direkt über UART ansteuern. Man benötigt die libnfc und diese Config in /etc/nfc/libnfc.conf:

# Set log level (default: error)
# Valid log levels are (in order of verbosity): 0 (none), 1 (error), 2 (info), 3 (debug)
# Note: if you compiled with --enable-debug option, the default log level is "debug"
log_level = 2

# Manually set default device (no default)
# To set a default device, you must set both name and connstring for your device
# Note: if autoscan is enabled, default device will be the first device available in device list.
device.name = "nfcfoo"
# ggf. anpassen
device.connstring = "pn532_uart:/dev/ttyUSB0"
