NFC PN532 Module RFID Near Field Communication Card Reader 13.56MHZ Compatible with Arduino

NFC PN532 Module RFID Near Field Communication Card Reader 13.56MHZ Compatible with Arduino


Description:
Communication with labels
- Module must be connected to the control panel STM32F1OX when the label readmg and writtmg communication, the communication system is the default UART. More wirmg can refer to the instructions in processing routine code.
- Wiring Description: PD3 pin is buzzer, button pin PC6 PD13, PD14; LED is PA4 、 PA6 、 PA7
- Operating instructions: Write label function, press KEY2, D2 status indicator lights. Let label close to the antenna ， then you can write data(OxAA) to the label, the buzzer will tick when written successfully.

Function:
- PN532 module is an NFC (short range Wlreless commumcatlons technology) module, chip Introduced by NXP which applied in13.56MHZ contactless communication and highly integrated IC card reader chip, with 40 B ROM and 1 kB RAM of 80C51 micro controller core supports all layers of the protocol regard ISO14443 Type A and Type B.

Feature:
- In the Reader mode, supports Mifare Classic encryption
- Support 212kbit/s and 424 kbit/s data transfer rate
-  Under FeliCa mode, support 106kbit/s, 212kbit/s and 424 kbit/s communication baud rate
- Support Host Interface: SPI interface, I2c interface, serial UART
- Operating voltage: 2.7V-5.5V


Operating instruction:
The module have three kinds of communication: SPI IIC, UART.
NOTIC: The figure in the middle 2X3 double needle is IO and I1, the left is GND （0） ： the right is VCC (l)

Commumcation between modules:
This module can communicate with each other. The communication system is
the default UART Connect with PC through USB to TTL module .  
1. First, connect the two PN532 modules with USB to TTL module (PL2303,FT232,etc.） separately, then connected to the computer via USB interface
2. Open the PC software CORX-NFC-P2P.exe twice. Choose port respectively;
3. Respectively choose the Initiator side and the target side on two PC software, select content to send In the Input port and click
4. The two PN532 antenna modules closes to each other,the computer screen will automatically pop up the received content;
5. Write label function, press KEY3, D3 status indicator lights. Let label close to the antenna, then you can write data(Ox55 ） to the label, the buzzer will tick when written successfully.
6. Reading the label function, press KEYI, D1 status indicator lights. Let label close to the antenna, then you can read the data of fixed position from label
if what it reads out is OxAA then lit D4, if what it reads out is 0x55, then extinguished D4, the buzzer will tick when read successfully.

Package included:
1xNFC PN532 Module with cable
