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.
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 groundConnect to ESP32: (INMP441 ESP32)
