Anybody got the diagram for this TPA3116 bluetooth board?
Trying to run its built-in bluetooth module through an isolated power source because I believe that's the main source of the hiss while playing through bluetooth.
And if there is any common good mods for it I would greatly appreciate it!

Thats interesting, what power supply do you use? I've tried a 19v laptop brick and a 12v transformer, I got bluetooth hiss with both!
I use a brick for now. I recently bought one of these, but haven't hooked it up yet.

I've been very impressed with this amp. I'm using it with the subwoofer/bass section turned off right now, but have used it with the sub as well. Bummer about the hiss for you. Are you still within a reurn/exchange window?

I also have get same board six month ago . And did a lot of mod on it .
The board may hiss when use different adapter . Finally with Dell Notebook adapter (19.5V/130W) then it quite on my side..
Here are some diagrams get from forum (Thanks forum !) related the board. Hope it have some help.
Some diagram is "early version of board" schematic not full match the one you have ,but some part still could reference
