- 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!
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. For many microcontrollers, adding audio input is easy with one of our analog microphone breakouts. 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. Instead of an analog output, there are three digital pins: Clock, Data and Left-Right (Word Select) Clock. 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.
This is a single mono element, so if you need stereo, pick up two microphones! You can set them up to be stereo by sharing the Clock, WS and Data lines but having one with Select to ground, and one with Select to high voltage. Many beginner microcontroller boards don't have I2S, so make sure its a supported interface before you try to wire it up! This microphone is best used with Cortex M-series chips like the Arduino Zero, Feather M0, or single-board computers like the Raspberry Pi.
