The ITEAD PN532 NFC module, as its name implies, is based on the PN532 chip for near field communication at 13.56 MHz. 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 NFC library supporting Arduino and the Raspberry Pi we offer, the development of NFC-enabled products is very convenient.
