RAK7289C Identifying hardware version

Hi,

I have a RAK7289C with Wisgate OS v1.3.9.

How do I confirm the hardware version of V1 or V2? Will it be displayed on the product label? It was not explicitly specified in my order from a supplier.

Is it possible to upgrade to Wisgate OS v2.x.x> or is it a hardware limitation?

Many thanks,
Hayden
