Itead pn532 NFC module, as its name implies, is based on pn532 chip, used for 13.56MHz near-field communication. The module is equipped with an onboard antenna, so there is no external antenna coil. It is compatible with SPI, IIC and UART interfaces for communication. With the development of Arduino and raspberry PI supported by NFC library, it is very convenient to use NFC products.
