5Pcs INMP441 Omnidirectional Microphone Module MEMS High Precision Low Power I2S Interface Support ESP32 Product introduction:_x000D_ The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. The_x000D_ The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows the INMP441 to be connected directly to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system._x000D_ The INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications. The INMP441 has a flat wideband frequency response that results in high definition of natural sound._x000D_ Product Features:_x000D_ Digital I2S interface with high precision 24-bit data_x000D_ 2.
