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.
