Low signal amplifier.
The amplifier worked as expected. I'm very satisfied.

I wish I had a schematic or spec sheet
It seems to have a lowpass filter in it at 1800 hz. I didn’t know that and my signal is 3000 hz 🙁.The chip can run all the way to 10khz easy. So now I have to pick capacitors off the board or find a simple linear small signal amp somewhere else😕. Not 100% sure what makes the blue led come on. Simple 5/Gnd doesn’t make it come on until a signal is connected
