PN532 NFC module as its name implies is based on PN532 chip and used for 13.56MHz near field communication. The module is equipped with onboard antenna thus no external antenna coil is needed. It is compatible with SPI IIC and UART interface for communication. With NFC library support for Arduino. and Raspberry Pi offered by us it is quite convenient for development of products with NFC functions. NFC module is equipped with double-row pin which can be connected directly to the Raspberry Pie via connection cable and then drive the module for non-contact near field communication operations such as reading and writing 13.56M IC card with our PN532 NFC SPI Library.
