PN532 NFC MODULE

PN532 NFC Module is a highly integrated radio transmission module for Near Field Communication at 13.56MHz. NFC (Near Field Communication) protocol designed for smartphones and similar devices, can read and write cards and tags, interact with NFC phones, and enable communication from device to device. PN532 NFC Module establishes radio communication with each other by touching them together or bringing them into contact, usually no more than a few centimetres. As a result, it provides simple and fast data exchange between devices. The switch-mode on the module board, change easily between I2C, SPI, and UART modes. Moreover, it supports RFID reading and writing, and NFC function with Android phone, which makes it accurate for a wireless connection. Therefore also known as short-range radio communication.

PN532 MODULE uses to establish NFC communication. PN532  NFC RFID (Radio Frequency Identification) module built around NXP PN532 IC, acts as a modem to send and receive data. This technology consists of a contact-free radio frequency identification (RFID), providing M2M (Machine to Machine) communication. Sony and Philips first developed this mainly for mobile phones and other handheld devices. The PN532 combines a modulation and demodulation concept for different kinds of contactless communication methods and protocols at 13.56 MHz. In the PN532 module, first, we will choose the mode of communication between MODULE and CONTROLLER. As this module has three interfaces, of which we have to choose one. At a time only one of three interfaces used. Two switches solder to the board selects the mode of the interface.
