tRF
1. Introduction
tRF Click is an add-on board in mikroBUS
™
form factor. It's a compact and easy solution
for adding 868MHz RF communication
to your design. It features the Telit
LE70-868 - 868MHz transceiver module,
an SMA connector for an antenna as well
as two radio communication LEDs. tRF
Click communicates with the target board
™
mikroBUS
microcontroller via UART (Rx,
™
Tx), AN, RST, PWM and INT lines. The board
is designed to use 3.3V power supply only.
A LED diode serves as a power indicator.
2. Soldering the headers
Before using your click
™
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
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.

3
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 the 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 the pins are aligned
™
correctly, push the board all the way
into the socket.

4. Essential features
tRF Click with LE70-868
™
868MHz RF transceiver module with an
embedded stack that is easy to integrate
and use in point-to-point or star network
topologies. The board enables radio data
rates from 4.8 to 57.6 kbps with maximum
output power of 500mW and a range of
over 4000 meters (maximum tested range)
in open space. The board contains radio
transmit (red) and receive (yellow) LEDs.
