About this product
A microphone element for picking up sound in audio, voice and recording projects. It converts sound waves into an electrical signal that is usually conditioned by an amplifier stage before a microcontroller or audio circuit can process it. The listing gives no model, sensitivity or pinout, so check the datasheet before wiring.

Frequently asked questions
Can I connect it directly to an Arduino or ESP32 pin?
In most cases, no. The signal is very small and usually needs a bias network and an amplifier stage, such as an op-amp or a dedicated amplifier module, before it reaches an ADC input.
How do I know which type of microphone element I have?
The listing does not say whether it is electret, MEMS or dynamic. Check the markings on the element or its datasheet, because the wiring and biasing differ between types.
