INMP441 I2S microphone module

Product detailed description

INMP441 module I ² S microphone

Microphone module suitable for connection to ESP8266, ESP32 or other microcontrollers with I²S interface.

The module has a switching pin L/R, which selects to which I²S channel the signal from the microphone will be routed. If the pin is at logic level L, the microphone output is routed to the left stereo channel I²S. If the pin is at logic level H, the output of the microphone is routed to the right I²S stereo channel. The module does not allow routing to both stereo channels.
