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. | |
