RAK 4630/1 Wisblock - Anyone reviewed/feedback

Hey All,
Has anyone tried the Rak Wisblock LPWAN module out and tested on TTN or other LoRaWan?

I see that RAK have a API for it (not open source): LoRaWan-RAK4630.h

Usual questions:…

Power consumption, Class C, LoRwan Spec, Compliance, Duty-cycle, regional parameters etc.

Insights would be very interesting.
Cheers

There’s quite a lot of discussion plus the documentation, GitHub repro etc over on the RAK forum …
