Hi all, 
The project I am working on wants to use LoRa or LoRaWAN to transfer data from the Ubuntu on the Sentinel to a computer running Ubuntu. What is the best way to add this functionality to the Sentinel? 

My current thoughts are to do one of the following

Create a custom PCB and use the built in I2C or UART connectors to communicate with it.

Use a USB dongle. (The downside is we would loose wifi connectivity, which I do not think my team is willing to do.)

Attach a Raspberry Pi and let it connect to the Sentinel via wifi and translate packages to LoRa

Thank you for your help.

VOXL 2 has a lot of I/O which can be used to communicate with many different devices. We would need to know what interfaces your LoRA radio supports in order to suggest how to connect the two.

@Chad-Sweet Thank you for getting back to me. 

The radio we are leaning to use has an SPI interface. However, I am not opposed to switching radios if there is an easier to use I/O on the VOXL. 

We are leaning to using Adafruit RFM95W based on the SX1276 LoRa®  module with SPI interface.
