2. Soldering the headers
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.
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
the 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.
4. Essential features
LoRa wireless technology enables low power
consumption and a long range. The RN2483
transceiver module has a specied range of
>15km in rural and suburban settings, and
>5km coverage in urban areas. A LoRaWAN™
Class A protocol stack is embedded
(bidirectional end devices), as well as an ASCII
command interface accessible through UART.
The high receiver sensitivity can go down to
-148 dBm. Applications include Automated
Meter Reading, Home and Building Automation,
M2M, IoT, Industrial Monitoring and Control.

LoRa RF click carries Microchip’s RN2483
fully certied LoRa Sub-GHz, 433/868 MHz
European R&TTE Directive Assessed Radio
Modem. Two antenna connectors allow
you to choose which of the two frequency
bands will be employed. LoRa RF click
communicates with the target board MCU
through the mikroBUS™ UART interface (CTS,
TXD, RXD), with the addition of a Reset pin
(RST). The board is designed to use either a
3.3V or a 5V power supply.
