Description: Digital I2S interface with high precision 24-bit data High signal to noise ratio is 61 dBA High sensitivity - 26 dBFS Stable frequency response from 60 Hz to 15 kHz Low power consumption: low current consumption 1.4 mA High PSR: -75 dBFS Interfaces: 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 How to connect to ESP32 with I2S: Connect to ESP32: INMP441 ESP32 SCK >> GPIO14 SD >> GPIO32 WS >> GPIO15 L/R >> GND GND >> GND VDD >> VDD3.3 Package included: 3 * INMP441 Omnidirectional Microphone Module
