I have a doubt regarding RAK2287 concentrator. I bought AU915 version but now I am requiring to use EU868.
From the datasheet I understand that the RAK2287 supports many regions and these are configurated by firmware:
But I noticed that the board has in the silkscreen the labels EU868 and AU915, each one with a resistor on its side. My RAK2287, for example, has only assembled the resistor that’s labeled as AU915:
(I hope you can see the resistor in the image)
On the other hand, on the RAK store web page, the images show that the resistor assembled is the one labeled as EU868:
So, my question is: does the frequency selected on the RAK2287 depend merely on firmware configuration or does it depends on a hardware configuration?
For EU868 can I use my RAK2287 purchased as AU915?
Thank you for your help.
