The PN532 NFC V3 RFID module allows not only to read and write information from Mifare RFID cards, tags and key fobs operating at a frequency of 13.56 MHz, but also exchanges data with other devices that support NFC (Near Field Communication) technology. The module is based on the PN532 chip and supports ISO14443 Type A/B wireless protocols. It can be used in room access control systems, security systems, as part of a smart home, robot positioning systems, etc. To connect the module, UART, I2C or SPI interfaces are used. When using the interrupt signal, when connecting the module, only three pins of the controller are used.

Main characteristics:

Chip: PN532
Logic: CMOS, 3.3V
Supply voltage: 3.3-5V
Maximum current consumption: 150 mA
Standby current consumption: 100mA
Current consumption in read mode: 120 mA
Current consumption in recording mode: 120 mA
Reading range: 5 - 7 cm
Antenna: built-in, on-board
Dimensions: 42.7 x 40.4mm
Interface support: I2C/SPI/HSU (High Speed UART - 115200 kbps)

Supported operating modes:

RFID (read/write)
P2P connections
NFC for working with smartphones on the Android platform

Chip support:

ISO 14443 Type A - NXP Mifare 1k, 4k, Ultralight, Desfire
ISO 14443 Type B
ISO/IEC 14443-4 compliant chips
FeliCa
Jewel
TopaZ

The module supports multiple interfaces. in order to connect the module via the I2C bus, change the position of the switch according to the table next to it.

Arduino code example:

#include <Wire.h> // include the library for I2C
#include <Adafruit_PN532.h> // include the library for working with the module
#define PN532_IRQ (2) // specify the pin to which the IRQ pin is connected
#define PN532_RESET (3) // specify the pin to which the RST pin is connected
Adafruit_PN532 nfc (PN532_IRQ, PN532_RESET); // assign a name to the module

void setup() {
Serial.begin (115200); // initiate data transfer to the serial port monitor at 115200 baud
Serial.println ("Hello!"); // print the text to the port monitor
nfc.begin (); // initiate work with the module
uint32_t versiondata = nfc.getFirmwareVersion (); // read the firmware version of the module into a variable
if (! versiondata) {// if the variable is empty, then
Serial.print ("Didn't find PN53x board"); // print the text to the port monitor
while (1); // interrupt further execution of the setup block
  }
Serial.print ("Found chip PN5"); Serial.println ((versiondata >> 24)&0xFF, HEX); // if the version is read, then display the text and the version of the chip in the port monitor
Serial.print ("Firmware ver."); Serial.print ((versiondata >> 16)&0xFF, DEC); // display the text and firmware version to the comma in the port monitor
Serial.print (','); Serial.println ((versiondata >> 8)&0xFF, DEC); // display the comma and the firmware version after the comma
nfc.setPassiveActivationRetries (0xFF); // set the number of attempts to read the card
nfc.SAMConfig (); // configure the module to read RFID tags
Serial.println ("Waiting for an ISO14443A card"); // print the text to the port monitor
}
void loop() {
boolean success; // set a variable for reading the card number
uint8_t uid [] = {0, 0, 0, 0, 0, 0, 0}; // set a variable to store the number of the read card
uint8_t uidLength; // length of the card number (4 or 7 bytes depending on the type of card)
success = nfc.readPassiveTargetID (PN532_MIFARE_ISO14443A,&uid [0],&uidLength); // read the first card to determine the size and purpose of the card type
if (success) {// if the number is read, then
Serial.println ("Found a card!"); // print text to the port monitor that the card has been found
Serial.print ("UID Length:"); Serial.print (uidLength, DEC); Serial.println ("bytes"); // display the text and the value of the card length in bytes
Serial.print ("UID Value:"); // print the text to the port monitor
for (uint8_t i = 0; i <uidLength; i ++) {// display the card number (depending on the length of the number, the number of times that the loop should perform will also change)
Serial.print ("0x"); Serial.print (uid [i], HEX); // display text and bitwise card number
    }
Serial.println (""); // add newline character
delay (1000); // wait 1 second
  }
else {// if the card was not read, then
Serial.println ("Timed out waiting for a card"); // display text to the port monitor that the card has timed out
  }
}
