mikroElektronika RFid click MIKROE-1434 User manual

1. Introduction
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
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down so that
bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
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.

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.
RFid click
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.

6. SMD jumpers
5. RFid click™ Board Schematic
Two SMD jumpers are
provided on the board. In
case you want to use UART
interface, it is necessary
to solder SMD jumpers in
Bposition. 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.
