Anyone have any luck with this? I cannot get any response (LED or signal) from it.
It is strange, looks like a BLANK white PC board, with only a 5–3.3v regulator and one chip with 2 leads.
Where’s the ‘smarts’ and antenna?
I found a better one with specs and visible chips on it and have it on order.
If so, it looks like you need to solder some bluetooth module to it. All those little pieces of exposed metal are pads that allow a chip to be soldered.
