Tír Na HiFi

Starting a new thread since it's a different product. The board itself costs only 88 RMB, maybe that's a good deal?

They've got an app for the Bluetooth 4.2 part as well, though that might not be good for SQ?

Anyone tried it yet?

I don't see any audio freq clocks on them
I'd be looking for that

must be more on the back side - that looks like an arduino HC06 bluetooth module

Volume control at the source end too.

Is there any pics of the other side?

Couldn't find any.....

I have a similar board with the same module, wrote about it on my blog last year : http://www.diyaudio.com/archive/blogs/c ... t3972.html

It runs fairly hot so I'd guess it gives out a fair amount of EMI.
