5-piece INMP441 omnidirectional microphone module

5-Piece INMP441 Omnidirectional Microphone Module Product Introduction: The INMP441 is a high-performance, energy-efficient, omnidirectional MEMS microphone with a digital output and bottom-mounted connector. The INMP441 complete solution consists of a MEMS sensor, signal conditioning, analog-to-digital converter, anti-aliasing filter, power management, and an industry-standard 24-bit I²S interface. Thanks to the I²S interface, the INMP441 can be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec. The INMP441 features a high signal-to-noise ratio and is ideal for near-field applications. Its linear broadband frequency response ensures high resolution and natural sound reproduction. Product Features: Digital I²S interface with high-precision 24-bit data 2. High signal-to-noise ratio (61 dBA) 3. High sensitivity (-26 dBFS) 4. Stable frequency response from 60 Hz to 15 kHz Low power consumption: 1.4 mA 6. High PSR: -75 dBFS Interface Definition: SCK: Serial data clock for the I²S interface WS: Serial data word selector for the I²S interface L/R: Left/right channel selector. When set to "Low", the microphone outputs a signal on the left channel of the I²S frame. When set to "High", the microphone outputs signals on the right channel. SD: Serial data output of the I²S interface. VCC: Input voltage, 1.8 V to 3.3 V. GND: Ground Connection to ESP32: INMP441 ESP32 SCK – GPIO14 SD – GPIO32 WS – GPIO15 L/R – GND GND – GND VDD – VDD3.3 Color: Black Material: ABS Package Contents: 5 x Omnidirectional Microphone Module Only the above package contents are included; other products are not included. Note: Due to different lighting conditions and monitor settings, the color of the item in the picture may differ slightly from the original. The measurement deviation is +/- 1-3 cm.
