INMP441 MEMS Omnidirectional Microphone Module I2S Interface Support ESP32
The INMP441 MEMS Omnidirectional Microphone Module is a high-performance audio sensor designed for precise sound capture in a variety of applications. With its Micro Electro Mechanical Systems (MEMS) technology and I2S interface, this module delivers superior audio quality and is particularly well-suited for use with ESP32 microcontrollers.
Features
- Digital I2S interface with high-precision 24-bit data
- High signal-to-noise ratio of 61 dBA
- High sensitivity -26 dBFS
- Stable frequency response from 60 Hz to 15 kHz
- Low power consumption: low current consumption of 1.4 mA
- High PSR: -75 dBFS
Interface definition
- SCK : Serial data clock of I2S interface
- WS : Serial data word selection for I2S interface
- L/R : left/right channel selection.
- When set to low level, the microphone outputs signals on the left channel of the I2S frame.
- When set to high level, the microphone outputs the signal on the right channel
- SD : Serial data output of I2S interface.
- VCC : Input power, 1.8V to 3.3V.
- GND : power ground
