Specifications Parameter Value Chipset PN532 Operating Frequency 13.56MHz Supported Protocols ISO/IEC 14443A/B, MIFARE, FeliCa Communication Interfaces I2C, SPI, HSU (High-Speed UART) Operating Voltage 3.3V–5.5VDC Max Operating Current 150mA Operating Distance Up to 50mm (depending on antenna and tag) Dimensions 43mm x 41mm PINOUT Pins Details VCC VCC is to power up the whole device. GND GND pin helps to make the common ground with power supply and the Arduino/Microcontroller. UART Communication Pins TXD UART communication requires two communication pins one for transmitting data and second for receiving it. TXD helps to transmit the data. RXD The RXD pin is the data receiving pin of the UART communication. I2C Communication Pins SDA I2C communication requires one pin for data transmission and receiving. Therefore, in the PN532 module SDA is a data pin for I2C communication. SCL SCL is the clock pin of I2C communication. Data travel between devices according to the clock pulse. IRQ IRQ pin is an interrupt pin, which helps to I2C communication to generate the interrupt to get the attention of the Arduino/Microcontroller. RST RST is a reset pin, which helps to reset the device through an external signal. In PN532 this device is for I2C communication. SPI Communication Pins MOSI SPI communication requires 4-pins for data communication. Therefore, MOSI is a Master Out Slave In pin, it helps to transmit data from Arduino to PN532. MISO MISO is a Master In Slave Out, it helps to transmit data from PN532 to Arduino. SS SS is a slave select pin; it activates the SPI communication of the Slave (PN532). SCK It’s a clock pin, helps in Tran receiving of data according to the clock pulse. Applications Access control systems and secure identification. Contactless payment terminals and ticketing systems. NFC-enabled device communication and data exchange. Smart posters and interactive advertising solutions. Inventory management and asset tracking. DIY electronics projects and prototyping.
