Hardware needed

You'll want a RAK baseboard and RAK11200 core

RAK19007+RAK11200 KIT (Make sure to pick 19007+11200 in the drop down)
BASE BOARDS
RAK11200

And then you will want the SDI-12 Module: RAK13010

RAK13010

If you want to use the SD card module, you will want to use the DUAL IO board ( RAK19001 )
