Why does a raw electret microphone need extra circuitry?
Electret condenser microphones need a bias voltage through a resistor and produce only a small signal, so they usually need an amplifier stage before an Arduino or Raspberry Pi can read them. Refer to the datasheet for the bias resistor value.
How do I identify the pins before wiring?
The listing does not specify pin assignment. Check the markings or the datasheet to identify the signal output and the ground terminal, and confirm polarity before connecting power.
