MEMS I2S Interface for ESP32 DIY Projects - Ultra-Small, High Precision, Low Power

Description:Features: brand new and high quality 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 for 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. Specifications: Digital with high-precision 24-bit data. High signal-to-noise ratio is 61dBA. High sensitivity -26dBFS. Stable frequency response from 60Hz to 15kHz. Low power consumption: low current consumption 1.4mAi. High PSR: -75dBFS. 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 Note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
