The library offers the developers to change the pins according to the board. In programming, the Arduino always depends on the library of PN532. Arduino programming tutorial for beginners.If you are a beginner with Arduino, read this complete guide: to use it with Arduino first to understand where the module should connect with Arduino. There’s a lot of work has and research on this module in Arduino. The most common and official recommendation for PN532 is to use it with Arduino broads. In most of the Airports, PN532 helps to identify the luggage, bags, etc.In most of the shopping malls, PN532 helps to identify the package.Security keys like cars, doors, etc are using the RFID module in a wide range.In mobiles, phone PN532 helps to exchange the data.

This supports the NFC of Android phones.The device has an onboard antenna and its size is smaller which helps to attach it anywhere in the device without covering too much space.There are three kinds of protocols in a single chip to make an interface with it.Onboard, switch helps to change the communication protocol.The device can operate with 3.3V for SPI and 5V for other communications.The module PN532 is useable as an NTAG/RFID Card Tag and reader.The RFID module uses 13.56MHz frequency and it is legal to use due to its small range.The PN532 allows the two modules to exchange any kind of data between each other at a specific distance.The features PN532 offers are mostly available in specific devices only and increasing daily due to their market demands. The device may be smaller in size but the features list of this device is much different and according to the modern applications. It’s a clock pin, helps in Transreceiving of data according to the clock pulse. SS is a slave select pin it activates the SPI communication of the Slave (PN532). MISO is a Master In Slave Out, it helps to transmit data from PN532 to Arduino. Therefore, MOSI is a Master Out Slave In pin, it helps to transmit data from Arduino to PN532. SPI communication requires 4-pins for data communication. In PN532 this device is for I2C communication. RST is a reset pin, which helps to reset the device through an external signal. IRQ pin is an interrupt pin, which helps to I2C communication to generate the interrupt to get the attention of the Arduino/Microcontroller. Data travel between devices according to the clock pulse. SCL is the clock pin of I2C communication. Therefore, in the PN532 module SDA is a data pin for I2C communication. I2C communication requires one pin for data transmission and receiving. The RXD pin is the data receiving pin of the UART communication. UART communication requires two communication pins one for transmitting data and second for receiving it. GND pin helps to make the common ground with power supply and the Arduino/Microcontroller.
