Product introduction:The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. TheThe 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.Product Features:Digital I2S interface with high precision 24-bit data2. High signal-to-noise ratio is 61 dBA3. High sensitivity-26 dBFS4. Stable frequency response from 60Hz to 15kHzLow power consumption: low power consumption 1.4 mA6.High PSR: -75 dBFSInterface definition:SCK: Serial data clock for I2S interfaceWS: Serial data word selection for I2S interfaceL / R: Left / Right channel selection.When set to low, the microphone outputs a signal on the left channel of the I2S frame.When set to high level, the microphone outputs signals on the right channelSD: Serial data output from the I2S interface.VCC: Input power, 1.8 V to 3.3 V.GND: power groundConnect to ESP32:INMP441 ESP32SCK--GPIO14SD--GPIO32WS--GPIO15L / R--GNDGND--GNDVDD--VDD3.3Colour:BlackMaterial:ABSPackage Contents:5 * Omnidirectional Microphone ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
