1.0 INTRODUCTION
RFM LoRa Shield is an Arduino shield which integrates RFM95W LoRa module and based
on Open Source Library with any Arduino projects. It is compatible with Arduino Uno,
Arduino Duemilanove,Arduino Mega2560,Arduino Leonardo and possibly other pin
compatible main boards.
RFM Lora Shield allows users to send data and reach extremely long ranges at low data-rates.
It provides ultra-long range spread spectrum communication and high interference immunity
whilst minimising current consumption, and targets professional wireless sensor network
applications such as irrigation systems, smart metering, smart cities, smartphone detection,
building automation, etc.
Using LoRaTM modulation technique, RFM Lora Shield can achieve a sensitivity of over
-148dBm using a low cost crystal and bill of materials. The high sensitivity combined with
the integrated +20 dBm power amplifier yields industry leading link budget making it
optimal for any application requiring range or robustness. LoRa also provides significant
advantages in both blocking and selectivity over conventional modulation techniques, solving
the traditional design compromise between range, interference immunity and energy
consumption.
Besides supporting high performance (G)FSK modes for systems including WMBus and
IEEE802.15.4g, RFM Lora Shield also deliver exceptional phase noise, selectivity, receiver
linearity and IIP3 for significantly lower current consumption than competing devices.
LoRa shield has stackable side headers which allows more Arduino-compatible shields to be
stacked on top of it. It also has built in grove sensors connectors which allows users to
integrate grove-based sensors into their application. It has also provided option for user to
integrate OLED with this shield for visual display.
* This is LoRa Radio Shield, the shield itself does not contain LoRaWAN, the Arduino
controller board (UNO, Mega, Leonardo, etc) will need to have LoRaWAN stack.
Features:
●Integrated with RFM95W LoRa module operating in the 915 MHz frequency band.
●High Receiver Sensitivity: down to -146 dBm.
●TX Power: adjustable up to +14 dBm high efficiency PA.
●FSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation.
●Low RX current of 10.3 mA, 200 nA register retention.
●The shield comes with:
○1 x SMA 90 deg antenna connector
○1 x U.FL SMD antenna connector
○1 x single through hole for wire antenna
●Interface via SPI with Arduino main board.
●3 Grove connectors for sensors or other grove-compatible devices.
●Option for OLED installment
●Suitable for low power wireless sensor network applications such as irrigation
systems, smart metering, smart cities, smartphone detection, building automation, etc.

5.0 HARDWARE INSTALLATION
This section will show example installation of LoRa-RFM-Shield with Arduino Uno as a
main controller. Besides Arduino Uno, other Arduino main boards such as Arduino
Duemilanove,CT-UNO,Arduino Mega2560 ,CIKU and CT-ARM are also compatible with
this shield.
5.1 Arduino Uno
Arduino is an open-source physical computing platform based on a simple I/O board and a
development environment that implements the Processing/Wiring language. LoRa Shield can
be used together with Arduino Uno. Figure below shows example hardware connection
between Arduino Uno and LoRa Shield; it is simply stacking up the shield onto the Arduino
main board.
1. Stack LoRa Shield on Arduino Uno. Ensure that the pins alignment is correct.
2. Install antenna as shown in the picture below.
