It's a Rii Mini Keyboard i4, and my concern is that it's a microphone. I just noticed the hole and think I'm probably wrong in what it is considering how big a deal it would be if it was a mic that isn't advertised.
What could this hole be for or what is it? Thanks in advance, hope this doesn't violate any rules.
I've looked through all of the keyboards on Riitek, I don't see any mention of this dot on any page or in any manual, but it consistently shows up on these mini keyboards with a dongle, so my guess is something to do with the wireless connection, but I'm not sure what. Another possibility is a screw hole, since there's only so much real estate on these tiny things, but that seems less likely.
