2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 NFC Tag click 2 3 4. Essential features 1. Introduction NFC (near field communications) is a radio standard for small data volumes and over limited ranges (with the particular PCB antenna on NFC Tag click , youll have a range of about 3cm). NFC also allows two-way communication. These features make NFC Turn the board upside down so that Turn the board upward again. Make sure the preferred standard for mobile payments, the bottom side is facing you upwards. to align the headers so that they are simple Bluetooth pairing and other connection Place shorter pins of the header into the perpendicular to the board, then solder handovers, or for social networking appropriate soldering pads. the pins carefully. applications, like exchanging vcards. NFC Tag click carries an M24SR64 NFC/RFID tag IC with a dual interface and 8KB of high-reliability EEPROM built-in. 3. Plugging the board in The RF protocol is compatible with both click NFC Forum Type 4 Tag and ISO/IEC Once you have soldered the headers your 14443 Type A, so theres three ways to board is ready to be placed into the desired BOARD operate it: 1) from an I2C interface 2) by a mikroBUS socket. Make sure to align the www.mikroe.com 13.56 MHz RFID reader or 3) from an NFC- cut in the lower-right part of the board with enabled smartphone, tablet, and similar the markings on the silkscreen at the NFC Tag click manual device. NFC Tag click communicates with mikroBUS socket. If all the pins ver. 1.00 the target board through mikroBUS I2C are aligned correctly, push the (SCL, SDA), INT and RST lines. It uses a 3.3V board all the way into the socket. 0 100000 027561 power supply only. 5. NFC Tag click board schematic 6.
