The larger Banggood module worked without any problem. With this one I have to change the Arduino Mega program. I'm using pin A0 and the threshold is not stable. Still looking for a solution. The mic and amp seem OK, though. Note that you must power it with 3.7volts. Not 5 volts!

Great value for money. As mentioned by another reviewer, this works off a 3.3V input. Output is roughly -1.5V to +1.8V. Sensitive to low power sound input.
