PN532 Module Near Field Communication Reader 13.56MHZ And Arduino Compatibility

Description:

PN532 module is an (short-range wireless communications technology) module, introduced by NXP which applied in 13.56MHZ, contactless communication and highly integrated IC card reader , with 40 B ROM and 1kB RAM of 80C51 micro controller core, supports all layers of the protocol regard ISO14443 Type A and Type B.

Features:

1.Reader mode, ISO/IEC 14443A/MIFARE mechanism
2.Reader mode, FeliCa mechanism
3.Reader mode, ISO/IEC 14443B/MIFARE mechanism
4.Card Operation mode, ISO 14443A/MIFARE mechanism
5.Card Operation mode, FeliCa mechanism
6.ISO/IEC18092, ECM340 Point to point

Performance :

In the reader mode, supports Mifare Classic
Supports 212 kbit/s and 424 kbit/s data transfer rate
Under FeliCa mode, 106kbit/s,212kbit/s and 424kbit/s communication baudrate
Integrates the interface of NFCIP-1 the transmission rate up to 424kbit/s
Host Interface: interface, I2C interface, serial UART
supply: 2.7V~5.5V
Board size: 50mmx120mm
Four positioning holes is , hole diameter is 3.25mm

Communication between module:

This module can communicate with each , the communication system is the default UART, Connect with PC through USB to TTL module, wiring as below:


Direction For Use:

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
4.The two PN532 modules close to each , the computer screen will automatically up the received content

Communication With Labels:

Module must be connected to STM32F10X the control panel when the label reading and writing communication, the communication system is the default URAT. More wiring can refer to the instructions in processing routine .
Writing Description: PD3 pin is buzzer, button pin PC6, PD13, PD14, LED is PA4, PA5, PA6, PA7

Operating instructions:

1.Write label function, press KEY2, D2 status indicator lights. Let label close to the , then you can write data(0xAA) to the label, the buzzer will drops when written successfully
2.Write label function, press KEY3, D3 status indicator lights. Let label close to the , then you can write data(0x55) to the label, the buzzer will drops when written successfully
3.Reading the label function, press KEY1, D1 status indicator lights. Let label close to the , then you can read the data of fixed position from label, if the read out is 0xAA, then lit D4, if the read out is 0x55,then extinguished D4, the buzzer will drops when read successfully
