RFid click
1. Introduction
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 CR95HF 13.56 MHz contactless
transceiver as well as 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.
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.

Turn the board upside down so that
bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS ™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at
the mikroBUS socket. If all of the pins are
™
aligned correctly, push the board all
the way into the socket.
4. Essential features
RFid click with its CR95HF IC is a RFid
™
module with integrated transceiver for
contactless applications. The board contains
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.
