Teyleten Robot INMP441 Omnidirectional Microphone Module MEMS High Precision Low Power I2S Interface for ESP32 (5PCS)

Product Features: 1. Digital I2S interface with high precision 24-bit data 2. High signal to noise ratio is 61 dBA 3. High sensitivity – 26 dBFS 4. Stable frequency response from 60 Hz to 15 kHz 5. Low power consumption: low current consumption 1.4 mA 6. High PSR: -75 dBFS Interface definition: SCK: Serial data clock for I2S interface WS: Serial data word selection for I2S interface L/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 channel SD: Serial data output of the I2S interface. VCC: Input power, 1.8V to 3.3V. GND: power ground . Connect to ESP32: INMP441 ESP32 SCK >> GPIO14 SD >> GPIO32 WS >> GPIO15 L/R >> GND GND >> GND VDD >> VDD3.3 Package includes: 5pcs x Microphone module

INMP441 is a high performance, low power consumption, digital output, omnidirectional MEMS microphone with bottom port
The complete INMP441 solution consists of a MEMS sensor, signal composition conditioning, analog-to-digital converter, anti-aliasing filter, power management and industry standard 24-bit I²S interface.
The I²S interface allows INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for the audio codec used in the system
INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. INMP441 has a flat broadband frequency response, resulting in high definition of natural sound.
