LoRa Radio Shield


The LoRa shied based on the RFM98W (433MHz/868MHz) module, which is a long-range transceiver on an Arduino shield form factor and based on Open source library. The LoRa Shield allows the user 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 minimizing current consumption.

Interface Function




These radio Wings do not have a built-in antenna. Instead, you have two options for attaching an antenna. For most low cost radio nodes, a wire works great. If you want to get a bettery quality signal you can connect a SMA interface antenna to it. Plug to Arduino or Maduino, connect the USB to the PC.[Hardware connection it is same as the LoRa Radio Shield(433MHz)Shield]


Load Demo

Basic RX & TX example

Let's get a basic demo going, where one Lora Radio Shield transmits and the other receives. We'll start by setting up the transmitter.

Open the Arduino IDE, select board -> Arduino Uno, and the correct Port.


  • Download the RadioHead library.

  • Open the sketch>include library> ADD.ZIP library

LoRa_Radio_Shieldunzip library.jpg

  • Choose the download path of RadioHead and unzip the library.

  • Get the 868MHz transmitter/Receiver code in here. Get the 433MHz transmitter/Receiver code in there.

  • Verify and upload the sketch.

Now open up the Serial console on the receiver, while also checking in on the transmitter's serial console. You should see the receiver is...well, receiving packets
