RF-LORA Semtech SX1272

Hi guys. I am kind a noowbie in RF moduls. I need little help. I have bought from farnell two FR-LORA Semtech Sx1272 moduls and I don't know to connect this moduls to arduino uno. Can anyone help me which pins i need to connect to which pins on arduino uno? Here is link to datasheet of the radio module:

I need sending simple messages between 3 arduinos uno. Two of them will be slaves and one will be master for showing messages from slaves.

And can anyone recommend a good library for thise radio muduls? Datasheet is alsou in attachment.

Many thanks for any help :slight_smile:

Do not cross post !
You have an identical post in section 'Project Guidance", https://forum.arduino.cc/index.php?topic=501571.0

You have the data sheet and if you read, you will see that the module has SPI, which you can connect to the Arduino SPI.

I do not know of any library, only because I have not searched.
I don't know Semtech hardware, except that the research I have done in past months suggest they would be well designed and reliable. A local company here near me uses them in locality based LoRa networks.

Keep searching :slight_smile:


A two minute online search will provide you with I think enough insight on how to make the SX1272 module work with Arduino.

For example, if I can find this, I am sure you can too: GitHub - matthijskooijman/arduino-lmic: This library is deprecated, see the README for alternatives.

It may not be the complete answer, but worth a good read.
Now, as I mentioned, go and search and put your time to good use and study.
