## Overview

The Adafruit I2S MEMS Microphone Breakout (SPH0645LM4H) is a compact, purely digital microphone module designed for high-quality audio capture. With a frequency response of 50Hz to 15KHz and a lightweight form factor of just 5 grams, it offers seamless digital integration via I2S output, eliminating the need for analog conversion. Perfect for modern audio projects requiring precision, portability, and cost-efficiency.

## Description

Listen to this good news - we now have a breakout board for a super tiny I2S MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This microphone doesn't even have analog out, its purely digital. The I2S is a small, low cost MEMS mic with a range of about 50Hz - 15KHz, good for just about all general audio recording/detection.

## Features

- Smaller and thinner than 'classic' electret microphones
- Low cost MEMS mic with a range of about 50Hz - 15KHz
- Good for just about all general audio recording/detection
- Purely digital, No analog conversion required!
