Assembled Product Weight

Specification: Features: The I2S is a small, low cost MEMS mic with a range of about 50Hz - 15KHz, 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. The microphone is a single mono . You can select whether you want it to be on the Left or Right channel by connecting the Select pin to power or ground. 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. Specification: Condition: VIN/logic: 3.3V Package List: 1 x Microphone Breakout Board Note: This I2S MEMS microphone is bottom ported, so make sure you have the hole in the bottom facing out towards the sounds you want to read. It's a 1.6-3.6V device only, so not for use with 5V logic its really unlikely you'd have a 5V-logic device with I2S anyways. 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 , Feather M0, or single-board computers.
