TPA3110 board not bad, needs tweaks

I’m talking about the cheap amp board you can get on Ali (see attachment). It is very loud for something so small, but…

The R+ and R- output is mislabelled, should be other way round, you can hear it, but if you can’t, following the data sheet for TPA3110 shows the mistake.

The heat sink, if hasn’t come off already, will. But there is plenty of space on each side of the chip to make 2 holes and screw heat sink properly, after making 2 threads in it, and you probably want to do this because when it pumps power it gets noticeably hotter.

Which brings me to my last point, you would want to add a large capacitor across power input. That is if you wanna push the board.
