INMP441 MEMS Microphone Module precision audio capture: delivers detailed sound with 26 dBFS sensitivity and 61 dBA signaltonoise ratio, providing accurate omnidirectional pickup for ESP32 projects in group or multisource environments. Low power consumption: operates at 1.4 mA, enabling longer battery life in mobile or remote devices and well suited for portable I2S interface applications with ESP32. Wide frequency response: from 60 Hz to 15 kHz, delivering natural sound by capturing both bass tones and clear highs, improving MEMS microphone performance in diverse recording scenarios. Integrated digital I2S interface: builtin 24bit I2S connectivity for direct integration with DSPs or microcontrollers such as ESP32, eliminating extra audio codec components and reducing system complexity. Compatibility and practicality: designed for ESP32 based projects requiring accurate omnidirectional sound pickup in group or multisource environments. Use scenarios ESP32 based conference or group voice capture for meeting room or classroom setups without external codecs. Portable voiceactivated devices, smart home assistants, or field recorders that operate on battery power and require efficient I2S audio capture. Robotics, drones, or remote sensing projects where robust omnidirectional audio input and simple DSP integration are advantageous.
