MS3625 Omnidirectional Microphone Module MEMS High-Precision And Low-Power I2S Interface Supports ESP32 Module

Features:1. Omnidirectional digital pickup: With high signal-to-noise ratio, flat broadband frequency response, and high clarity of collected sound.2. Easy to use: The I2S interface allows it to be directly connected to a digital processor, simplifying system design.3. High anti-interference ability: The power suppression ratio reaches -72 dBFS, and the output remains faithful even in strong noise environments.4. Intelligent channel configuration: L/R pin level switches between left and right channels, flexibly adapting to stereo systems.5. Widely applicable: Suitable for various speech collection scenarios, suitable for smart speakers, AI speech development and other scenarios.Product IntroductionThis sensor is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port, compatible with INMP441.Composed of a MEMS sensor, signal modulation, analog-to-digital converter, anti aliasing filter, power management, and industry standard 24 bit I2S interface. The I2S interface allows it to be directly connected to digital processors such as DSP and microcontrollers without the need for audio codecs used in the system. With high signal-to-noise ratio, it is an excellent choice for near-field applications. Having a flat broadband frequency response, resulting in high clarity of natural sound.Key Features:Input power supply 1.6V to 3.6VDigital I2S interface with high-precision 24 bit dataHigh signal-to-noise ratio of 61 dBAHigh sensitivity -26 dBFSStable frequency response from 60 Hz to 15 kHzLow power consumption: low current consumption of 1.4 mAHigh PSRR: -72 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 level, the microphone outputs a signal in the left channel of the I2S frame.When set to high level, the microphone outputs a signal in the right channel.SD: Serial data output of I2S interfaceVDD: Input power supply, 1.6V to 3.6VGND: Power GroundConnecting with ESP32 development board:This module - ESP32 development boardSCK -- GPIO14SD -- GPIO32WS -- GPIO15L/R -- GNDGND -- GNDVDD -- VDD3.3Product List:1X module2X3pin pin arrangement (optional non welded pin arrangement/welded pin arrangement)
