For the price, it is not worth it to build a assembly.
Mine didn’t come with instructions so I wrote one.
Pin 4: Digital Output
Pin 3: + 5 Volts
Pin 2: Ground
Pin 1: Analog Output
Adjust the potentiometer fully counterclockwise until you start hearing clicks (it might take 15 turns). The LED by the Pot should be off. Adjust the pot clockwise until the LED starts intermittently blinking.

I needed a sound detector for a particular application. I'm an electronic circuit designer with 40 years design experience and could have designed a circuit, but it was cheaper to just buy a PC board with the components to perform the function.
Don't believe the functional write up on this unit.

When I got the unit, I used it in my application and yes it worked! After tracing out the schematic (Note that I replaced the LM393 comparators with a similar device compatible with my simulator.) After studying the simple design, I realized that the potentiometer VR1 adjusts the dc voltage of the neg input to U1 so that the comparators are in the linear mode and can detect a signal. The problem here is that any variation in any parameter, i.e. supply voltage, ambient temperature, time of day, and the pot would have to be "re-tweaked" for it again to be able to detect a signal. The pot does NOT set the signal threshold as stated in the product write up. The good news is that I was able to redesign the circuit using some of the components, and it works fine!
