Description of product


RFid click features CR95HF 13.56 MHz contactless transceiver as well as trace antenna. The click is designed to run on a 3.3V power supply only. It communicates with the target MCU via mikroBUS™ UART (TX, RX), SPI (MISO, MOSI, SCK, CS) INT, RST, PWM and AN lines. The click functions as an integrated transceiver for contactless applications. The board contains a dedicated internal frame controller and analog front end (AFE) for RF communications. It supports ISO/IEC 14443 type A and B, ISO/IEC 15693 and ISO/IEC 18092 protocols (tags) as well as the detection, reading and writing of NFC forum type 1, 2, 3 and 4 tags.
