Quick Overview 

1. Module Size: 42.7mm x 40.4mm x 4mm
2. Easy to change mode: with a small SMD toggle Switch, it becomes very easy to change among IIC, SPI and HSU modes
3. Longer distance: the reading distance becomes 5~7cm, compared with 4~6 cm of last version
4. Built in PCB Antenna, with 5cm~7cm communication distance
5. On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI
6. Work as RFID reader/writer
7. Work as 1443-A card or a virtual card

Product Description

         The PN532 is a highly integrated transmission module for contactless communication at 13.56 MHz including microcontroller functionality based on an 80C51 core with 40 Kbytes of ROM and 1 Kbytes of RAM. 

          The PN532 combines a modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz with an easy-to-use firmware for the different supported modes and the required host controller interfaces.
