HiLetgo 3pcs INMP441 Omnidirectional Microphone Module High Precision 24 Bit Data I2S Interface Digital Output High Sensitivity
HiLetgo 3pcs INMP441 Omnidirectional Microphone Module High Precision 24 Bit Data I2S Interface Digital Output High Sensitivity
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
