Just like ''classic'' electret microphones, MEMS mics can detect sound and convert it to voltage, but they don''t need a bias resistor or amplifier, its all in one!
The SPW2430 is a small, low cost MEMS mic with a range of 100Hz - 10KHz, good for just about all general audio recording/detection.
This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT.
The output pin is not designed to drive speakers or anything but the smallest in-ear headphones - you''ll need an audio amplifier if you want to connect the amp directly to speakers
