Features:
The I2S is a small, cost-effective MEMS microphone with a range of around 50Hz to 15kHz, suitable for virtually all general audio recording/recognition. Instead of an analog output, there are three digital pins: Clock, Data and Left-Right (Word Select) Clock. When the I2S master is connected to your microcontroller/computer, it controls the clock and word selector pins at high frequency and reads the data from the microphone. The microphone is a single mono element. You can choose whether it should be on the left or right channel by connecting the select pin to power or ground. If you need stereo, take two microphones with you! You can set them up as stereo by sharing the clock, WS and data lines, but one with Select to Ground and one with Select to High Voltage.

1 x Microphone Breakout Board
Note:
This I2S MEMS microphone has a bottom opening. Therefore, make sure that the hole in the bottom faces outward to the sounds you want to read. It is only a device with a maximum of 1.6-3.6V, so not suitable for use with 5V logic (it is really unlikely that you have a 5V logic device with I2S anyway). Many beginner microcontroller boards do not have an I2S. Therefore, make sure this is a supported interface before trying to wire it! This microphone is best suited for Cortex M series chips such as zero, feather M0 or single-board computers.
