Seeedstudio Grove NFC Antenna Sensor Module Support Host Interface I2C / UART<br /><br />Main Features:<br />● Near Field Communication ( NFC ) is a set of short-range wireless technologies. It's behind daily applications such as access control system and mobile payment system.<br />● Grove NFC features a highly integrated transceiver module PN532 which handles contactless communication at 13.56MHz. You can read and write a 13.56MHz tag with this module or implement point to point data exchange with two NFCs.<br />● Grove NFC is designed to use I2C or UART communication protocols， and UART is the default mode.<br />● Support host interface: I2C， UART ( default ).<br />● Serve for contactless communication at 13.56MHz.<br />● Support ISO14443 Type A and Type B protocols.<br />● Max. operating distance for detecting NFC tags is 28mm depending on current antenna size.<br />● Support P2P communication.<br /><br />    Specifications<br />General<br />  Brand: Seeedstudio                                                  <br />                        Type: NFC Antenna Sensor Module                                                  <br />                        Compatibility: Ardunio                                                 <br />Electronic Components<br />  Operating Voltage: 3.3V                                                 <br />Weight and Size<br />  Product Weight: 0.011 kg                                                  <br />                        Package Weight: 0.065 kg                                                  <br />                        Product Size(L x W x H): 2.5 x 2 x 1 cm / 0.98 x 0.79 x 0.39 inches                                                  <br />                        Package Size(L x W x H): 9 x 6 x 1.2 cm / 3.54 x 2.36 x 0.47 inches                                                 <br />Package Contents<br />  Package Contents: 1 x Seeedstudio Grove NFC Antenna Sensor Module， 1 x NFC Antenna， 1 x IPX Connecting Wire                                                 <br /><br /><br /><br />                                                                                            <br />
