PN532 NFC RFID Module V3 Set with RFID Card and Key

The PN532 module reads RFID and NFC chips and can be addressed via UART (HSU), I2C or SPI. It works with type 1 to 4 chips as well as NXP MIFARE tags and can also simulate an NFC tag that can be read with an NFC-enabled phone. The board is marked Elechouse NFC Module V3. The set includes a card and a key fob.
