Arduino 13.56mHz PN532 Compatible With Raspberry Pie Board NFC Card Reader Module<br /><br />introduce<br />ITEAD PN532 NFC module, as its name implies, is based on the PN532 chips, used for near field communication 13.56 MHz. The module is equipped with on-board antenna, so there is no external antenna coil. It is compatible with SPI, IIC, UART interface for communication. As NFC library support Arduino and we are offering a Raspberry Pi with NFC is the development of products, it is convenient to use.<br />The characteristics of<br />The longest effective communication distance of 5 cm<br />Support for SPI, IIC, UART interface switching.<br />Can be used in the 13.56 M contactless communication<br />Compatible ISO14443 TYPE A and B class standard<br />specification<br />Chip NXP PN532<br />The working voltage of 3.3 V<br />The power supply voltage from 3.3 V to 5.5 V<br />The biggest power supply current is 150 ma<br />Working current is 100 ma (standby mode)<br />Working current 120 ma (write mode)<br />Working current 120 ma (read mode)<br />Pointer PWRS<br />Interface of the Raspberry Pi 20 pins interface standard SPI interface,<br />The board size: 79 mm long x 48 mm wide x 11 mm high<br />With package weight: 15.9 g<br />There are two slide switch selection interface on the board:<br />SET0 characters<br />UART L L<br />SPI L H<br />IIC H L<br /><img src="http://img6.eachbuyer.com/x9/p100/eb9594_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb9594_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb9594_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb9594_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb9594_5.jpg" />
