NFC Shield V2

 
NFC Shield is a Near Field Communication interface for Arduino build around the popular NXP PN532 integrated circuit. NFC is a short-distance radio technology that enables communication between devices that are held close together. NFC traces its roots in RFID technology and is an open platform technology standardized in ECMA-340 and ISO/IEC 18092.
 
NFC technology is regulated by Near Field Communication Forum which standardizes NFC communication between devices -- how they pair, share data and allow a secure transaction to happen.NFC Forum develops and certifies device compliance with NFC standards . NFC operate on ISM band of 13.56 MHz Frequency. NFC communication range is up to 10 cm. But, this is limited by the antenna and power radiation design. Most devices work within a range of 10mm. NFC Shield antenna is designed to work within a range of 1cm. NFC Shield provides all necessary circuitry for PN532 like 27.12Mhz crystal, power supply. It also beaks-out the I/O pins of PN532 for easy access. The communication between Arduino and NFC Shield is via SPI.
 
 
 
Features
  • Arduino Shield compatible. No soldering required.
  • SPI interface. Hence, most Arduino pins are available for other applications.
  • Built in PCB Antenna.
  • Supports both 3.3V and 5V operation using TI's TXB0104 level translator.
  • Socket to connect other shields.

seeedNFCshield not initialize with SDshield that are attached with arduinoUNO. What pins do I have to manipulate in order to make these two initialize at the SAME TIME?

Hi Ivan, since NFC Shield and SD Shield use the same SS(D10) on Arduino, you could disconnect D10 pin of SD Shield to Arduino , use a jumper connect it to other pin.

请问NFC shield能够和手机通信么??怎么操作??

您好,理论上是支持的,大多数手机的NFC都有它自己的底层协议,但都不是开源的,所以目前我们也无法使用它与手机通信。

What are the dimensions of this shield?

This is already included. When you add an expansion board of any model (e.g. 2.4GHz) the additional memory of the expansion board allows the 433M model to go from 420-450MHz. Please see http://tinyu
