How do I wire an electret microphone?
Electret microphones need a bias resistor, commonly around 2.2 kΩ as the listed impedance suggests, between the supply and the microphone's signal pin. The listing asks you to check the photo to identify the ground pin, so confirm polarity before powering it.
Can I connect it directly to an Arduino analog pin?
The output is a very small analog signal, so it usually needs an amplifier stage, such as an electret microphone amplifier board, before reading it with an ADC pin.
