This sensor is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. Compatible with INMP441

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

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

Note: Installation guide not included, we strongly recommend you seek professional installation. Please check as much as possible to make sure the item is what you need
