INMP441 I2S Omnidirectional MEMS Microphone Module for ESP32 Arduino and Raspberry Pi

Description

The INMP441 Omnidirectional MEMS Microphone Module is a high-precision digital microphone designed for audio capture, voice recognition, sound detection, and speech processing applications. Based on the INMP441 MEMS microphone chip, this module provides high-quality digital audio output through an I2S interface, making it ideal for ESP32, Arduino, Raspberry Pi, STM32, and other microcontroller projects. Unlike analog microphone modules, the INMP441 outputs a clean digital audio signal directly through the I2S interface, reducing noise and eliminating the need for an external analog-to-digital converter. This results in better sound quality and simpler integration with modern microcontrollers
