So i'm currently trying to take parts out of a Bluetooth speaker's circuit-board and find the Bluetooth module for a DIY project.


I looked at the board and some ICs and tried looking them up to no avail.

So How Do you read an IC or any other components on the board Or even find a schismatic of some-sorts!

Through hole semiconductors will typically have a complete part number. Surface mount will use a code that you need to look up, and the codes aren't unique between manufacturers.

Or even find a schismatic of some-sorts!

You start with the manufacturer. In the event that they won't provide one to discourage copying, you can trace the circuit and make a schematic. If there are unmarked components, you use connectivity to make an educated guess as to what it might be.

 

Wouldn't it be easier and more certain of success to buy a cheap bluetooth module like this: https://www.ebay.com/itm/Wireless-B...787618?hash=item3af0301ae2:g:AWYAAOSw4-hZr8Tj

BTW, you link doesn't show any specific item.
