3pcs INMP441 ESP32 Microphone, Omnidirectional Sensor Module with I2S Interface, Digital Microphone Module ESP32 Compatible, MEMS Audio Module for Arduino Projects High Precision Low
The INMP441 ESP32 microphone set of 3 provides powerful, omnidirectional MEMS audio modules for professional digital recording. Each INMP441 microphone module combines sensor, signal preparation, A/D converter and I2S interface in one energy-efficient system. As a digital microphone module ESP32 compatible, it eliminates the need for external codecs and significantly shortens development times. With high SNR, low power consumption and flexible channel control, the omnidirectional sensor module is ideal for voice assistants, IoT devices and maker projects. The compact SMD design allows space-saving integration into professional audio applications.
Product Features
- Digital microphone module ESP32 with professional I2S interface: The INMP441 omnidirectional microphone module Connects directly to ESP32 and microcontrollers thanks to the 24-bit I2S interface. No additional audio codec required - Industry standard-compliant digital transmission guarantees low-noise, high-resolution audio data in real time
- INMP441 Omnidirectional microphone for crystal-clear near-field recordings: With a signal-to-noise ratio of 61 dBA and -26 dBFS sensitivity, the INMP441 microphone module delivers superior audio quality. The flat frequency response from 60 Hz to 15 kHz allows natural voice reproduction in professional recording applications
- Energy saving INMP441 microphone module for mobile projects: At only 1.4 mA power consumption at -75 dBFS PSR This ESP32 microphone maximizes the battery life of battery-powered devices. The high efficiency makes it the ideal choice for IoT audio devices, voice assistants and portable recording systems
- Flexible omnidirectional sensor module with channel control: the L/R pin configure channel allocation via high or low level. The six connection pins (SCK, WS, SD, L/R, VCC 1.8-3.3V, GND) allow easy integration into stereo-enabled ESP32 and Arduino systems
- Compact INMP441 I2S interface module for SMD mounting: reflow solder compatibility allows the digital microphone module to be installed to save space. The halogen-free housing retains its full sensitivity even after the soldering process
