Actually, I have one of their PineA64 boards with an optional wifi/bt daughterboard. It's an awesome SBC. It actually has a built-in RTC, unlike many other SBCs (I'm looking at you, Pi bastards) and a built-in pass-through charging circuit, so you can just plug in a LiPo battery and start using it. It's a really nice SBC with a host of under-appreciated features.

I also have a PineBook, but I do not recommend that product to anyone. Terribly buggy keyboard, and the quality of the case is terrible, plus mine is now dead due to unknown causes. I still need to open it up to figure out what happened.
