Overview

For many microcontrollers, adding audio input is easy with one of our analog microphone

breakouts (http://adafru.it/1063). But as you get to bigger and better microcontrollers and microcomputers, you'll find

that you don't always have an analog input, or maybe you want to avoid the noise that can seep in with an analog mic

system. Once you get past 8-bit micros, you will often find an I2S peripheral, that can take

digital audio data

in! That's

where this I2S Microphone Breakout comes in.

Instead of an analog output, there are three digital pins: Clock, Data and Word-Select. When connected to your

microcontroller/computer, the 'I2S Master' will drive the clock and word-select pins at a high frequency and read out

the data from the microphone. No analog conversion required!
