We can't know what it is until you dump it and upload it. Maybe then we still don't know, or maybe someday we eventually do even if not today, but absolutely not if it never gets dumped. If it's just the eme adapter with no label, then it could be literally anything or nothing.
I don't sell REX's, I just tried to document the process of building, to remove all the mysteries and question marks and risk as much as possible so anyone could build their own, and put it where anyone else could improve the directions even further.
