5x Digital Omnidirectional MEMS Mic Sensor Compact Audio Pickup Unit Low Voltage I2S Link for Prototyping

This sensor is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. Compatible with INMP441 specifications. The module includes a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows connection to digital processors such as DSPs and microcontrollers without the need for an external audio codec. The device features a high signal-to-noise ratio. The device has a flat wideband frequency response. Main features: Digital I2S interface with 24-bit data High SNR of 61 dBA Sensitivity: -26 dBFS Frequency response from 60 Hz to 15 kHz Current consumption of 1.4 mA Power Supply Rejection Ratio: -72 dBFS Interface definition: SCK: Serial data clock for the I2S interface WS: Serial data word selection for the I2S interface L/R: Left/right channel selection SD: Serial data output for the I2S interface VCC: Input power, 1.6V to 3.6V GND: Power source Connection example for ESP32 development board: SCK -- GPIO14 SD -- GPIO32 WS -- GPIO15 L/R -- GND GND -- GND VDD -- VDD3.3 Color: As Shown Material: Plastic Package Contents: 5x Omnidirectional Microphone Module Note: Light reflection and different displays may cause the color of the item in the picture to differ from the actual product.
