Overview

An exotic new microphone has arrived in the Adafruit shop, a PDM MEMS Microphone! PDM is the 'third' kind of

microphone you can integrate with electronics, apart from analog or I2S. These microphones are very commonly used

in products, but are rarely seen in maker projects. Still, they have some benefits so we thought we'd offer a breakout

for the shop.

The first thing to note is that this sensor does not provide an 'analog' output like many of our electret microphone
