INMP441 Omnidirectional Microphone Module I2S Interface Low Power MEMS ESP32

The INMP441 is a high-performance, low power, digital-output, omnidirectional MEMS microphone with a bottom port. The INMP441 is available in a thin 4.72 x 3.76 x 1 mm surface mount package. It is reflow- solder compatible with no sensitivity degradation. The INMP441 is halide free. 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. SCK: Serial data clock for I2S interface; WS: Serial data word selection for I2S interface; L/R: Left/Right channel selection. Applications: Teleconferencing Systems; Remote Controls ; Gaming Consoles; Mobile Devices ;Laptops Tablets ;Security Systems 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 Included: 1 x INMP441 Omnidirectional Microphone Module I2S Interface Low Power MEMS ESP32
