Introduction
Note: This tutorial covers the latest version of the SparkFun Analog MEMS Microphone Breakout (
BOB-19389). We designed the updated version as a drop-in replacement so users with the previous versions of this breakout board (
BOB-9868 or
BOB-18011) can follow along with this tutorial. For specific details regarding the microphone ICs, refer to the Documents tab on their product pages or the previous release of this Hookup Guide:
The SparkFun Analog MEMS Microphone Breakout - SPH8878LR5H-1 is a simple and easy-to-use microphone for a variety of sound-sensing projects. The on-board microphone is a low-power, omnidirectional microphone with an analog output. It works for both near and long-range uses and is particularly good for portable applications due to its low power consumption. Possible applications include: smartphones, digital video cameras, and keeping an "ear" on your pets while you're away.
