Product description

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.

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.
