INMP441 I2S digital omnidirectional microphone module for ESP32, Raspberry Pi, and Arduino. Delivers high-quality digital audio input with low noise. Available at eleberric.com.
The INMP441 I2S Omnidirectional Microphone Module is a high-performance, low-power digital microphone that provides superior sound quality for audio recording and signal processing applications. Unlike traditional analog microphones, the INMP441 outputs digital audio data over the I2S interface, ensuring minimal noise interference and clean sound capture.
Built with an omnidirectional MEMS microphone, it can capture sound equally from all directions, making it perfect for voice recognition systems, smart home devices, sound level detection, and IoT projects. Its small size and easy integration with popular development boards such as ESP32, Raspberry Pi, and Arduino make it ideal for DIY makers and engineers building audio-based applications.
The INMP441 operates at 3.3V, with digital output compatible with most microcontrollers supporting I2S. It offers an excellent signal-to-noise ratio (SNR) and low total harmonic distortion (THD), ensuring accurate sound reproduction even in noisy environments. Whether you’re designing a speech recognition system, AI voice interface, or environmental sound sensor, this module provides the precision and performance you need.
