MS4030 Omnidirectional MEMS Microphone Module High Precise Low Power I2S Digital Output Compatible with INMP441

1. High performance digital I2S output, compatible with INMP441, facilitating system integration. 24 bit high-precision data, providing clear audio signals and natural sound quality performance. 3. High signal-to-noise ratio effectively reduces background noise interference. 4. High sensitivity, precise capture of near-field sound details. 5. Wide frequency response of 60Hz-15kHz, suitable for various speech acquisition scenarios. Main performance: Digital I2S interface with high-precision 24 bit data High signal-to-noise ratio: 61 dBA High sensitivity: -26 dBFS Frequency response: Stable frequency response from 60 Hz to 15 kHz Low power consumption: low current consumption of 1.4 mA High PSR: -72 dBFS It can be welded to the back panel for use, or directly used for surface mount welding Application scenarios: Suitable for smart home devices such as smart speakers and voice assistants, voice capture, integration into wearable devices, industrial environment acoustic monitoring, etc. Interface definition: 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 level, the microphone outputs a signal in the left channel of the I2S frame. When set to high level, the microphone outputs a signal in the right channel. SD: Serial data output of I2S interface VDD: Input power supply, 1.6V to 3.6V GND: Power Ground Connecting with ESP32 development board: This module - ESP32 development board SCK -- GPIO14 SD -- GPIO32 WS -- GPIO15 L/R -- GND GND -- GND VDD -- VDD3.3 Color: Black Material: PCB Package Contents: 1 * MS4030 Omnidirectional MEMS Microphone Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
