5G-M2 EVB kit documentation

I purchased 5G-M2 EVB kit with RM520N-GL module.
I found only 5G-M2 EVB User Guide v1,0 from Download Zone, but this guide does not match fully to my EVB v1.3 board.
Is there any newer version available on guide?

Also, I could not find anything specific to RM520 module.
However, AT Commands Manual v 1.2 seems to be valid.

Dear @JanS
For the user guide of M2, it doesn’t have any newer version, but most of all are the same. if you have any questions, please contact us, we will try to explain.

For the documents of RM520N, they don’t be uploaded to download zone.
