ICS-43434 I2S MEMS Microphone Module Breakout Low-cost low-pass filter

Experience crystal-clear digital audio with the ICS-43434 I2S MEMS Microphone Module Breakout. This ultra-compact, bottom-ported mic is designed for modern microcontrollers and computers that support digital I2S input. Delivering a frequency response of 50Hz–15kHz, it’s perfect for general-purpose audio capture. With a built-in low-pass filter that eliminates frequencies above 24kHz and selectable left/right channel configuration, it’s ideal for mono or stereo setups. No drivers or analog conversions needed—just clean 24-bit digital output. With high signal-to-noise ratio, low power consumption, and a footprint smaller than a dime, this mic is your go-to solution for embedded sound sensing.
