RFid click

RFid Click™ is an accessory board in mikroBUS™ form factor. It's a compact and easy solution for adding RFid to your design. It features a CR95HF 13.56 MHz contactless transceiver as well as a trace antenna. RFid click™ communicates with the target board microcontroller via mikroBUS™ UART (TX, RX), SPI (MISO, MOSI, SCK, CS) INT, RST, PWM and AN lines. The board is designed to use 3.3 V power supply only. LED diode (GREEN) indicates the presence of power supply. CR95HF IC is a RFid module with an integrated transceiver for contactless applications. The board contains a dedicated internal frame controller and an analog front end (AFE) for RF communications.

RFid Click™ is an accessory board in mikroBUS™ form factor. It’s a compact and easy solution for adding RFid to your design. It features a CR95HF 13.56 MHz contactless transceiver as well as a trace antenna. RFid click™ communicates with the target board microcontroller via mikroBUS™ UART (TX, RX), SPI (MISO, MOSI, SCK, CS) INT, RST, PWM and AN lines. The board is designed to use 3.3V power supply only. LED diode (GREEN) indicates the presence of power supply. CR95HF IC is a RFid module with an integrated transceiver for contactless applications. The board contains a dedicated internal frame controller and an analog front end (AFE) for RF communications.

The CR95HF has 2 operating modes: Wait for Event (WFE) and Active.

In Active mode, the CR95HF communicates actively with a tag or an external host. WFE mode includes four low consumption states: Power-up, Hibernate, Sleep and Tag Detector. The transceiver can switch from one mode to another.

The Hibernate state has the lowest power consumption out of the four states (1 µA typ. 5 µA max.).

SMD Jumpers

Two SMD jumpers are provided on the board. In case you want to use UART interface, it is necessary to solder SMD jumpers in B position. Otherwise, if you want to use SPI interface, jumpers should be left in its default position (A). In that case interrupt pins (IN and OUT) are usable.

The board can be used with 13.56 MHz RFid tags or identification cards. Ideal for tracking and security systems that needs RFID support.

Key features

  • CR95HF 13.56 MHz contactless transceiver with trace antenna.

  • Dedicated internal frame controller and analog front end (AFE) for RF comm. available on-board.

Key Benefits

  • mikroBUS™ form factor enables easy integration.
  • Supported in mikroElektronika compilers.
  • Ready-to-use examples save development time.
