I have salvaged this Bluetooth module form an "old" speaker. I've searched everywhere on the internet and typed in the serial number on, it but it is nowhere to be found. Can some of you maybe identify it? or maybe even have a datasheet on it?

 

Likely obtainable here.... good luck...

I'm Afraid not. Could there be any reason to why i can't find it anywhere?

Sure.. They don't release that stuff to the general public.. Thats quite common..
Thats the company that makes it though.. well the main chip anyways..

And microchip bought them out in 2014 and well.. thats life..

... So my best shot is just to guess what the pins do..?

 

Buy a new one - trying to mess with unknown and undocumented hardware is a sink hole for your precious life energy.

They are really cheap

Well i mean i've still got the PCB Where i got the Module from. it says where RXD, TXD and GND, can be found but a data sheet would still be nice, for all of the functions and such.
