- Model: NFC / RFID Shield<br />- Quantity: 1<br />- Color: White<br />- Material: Glass fiber FR4<br />- 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<br />- NFC Forum develops and certifies device compliance with NFC standards<br />- NFC operate on ISM band of 13.56MHz frequency<br />- NFC communication range is up to 10cm. But、 this is limited by the antenna and power radiation design<br />- Most devices work within a range of 10mm<br />- NFC Shield antenna is designed to work within a range of 2cm<br />- NFC Shield provides all necessary circuitry for PN532 like 27.12Mhz crystal、 power supply<br />- It also beaks-out the I/O pins of PN532 for easy access<br />- The communication between Arduino and NFC Shield is via SPI<br />- Arduino Shield compatible<br />- No soldering required<br />- PI interface. Hence、 most Arduino pins are available for other applications.<br />- Built in PCB Antenna.<br />- Supports both 3.3V and 5V operation using TI's TXB0104 level translator.<br />- Socket to connect other shields.<br />- Packing list:<br />- 1 x Communication module<br />- 2 x 6pin headers<br />- 2 x 8pin headers<br />- 1 x Philips mifare card<br /><br />                                                                                                                                Dimensions: 2.95 in x 2.17 in x 0.43 in (7.5 cm x 5.5 cm x 1.1 cm)<br />Weight: 0.85 oz (24 g)<br /><br />
