High performance digital I2S output, compatible with INMP441, facilitating system integration. <br \/>24 bit high-precision data, providing clear audio signals and natural sound quality performance. <br \/>3. High signal-to-noise ratio effectively reduces background noise interference. <br \/>4. High sensitivity, precise capture of near-field sound details. <br \/>5. Wide frequency response of 60Hz-15kHz, suitable for various speech acquisition scenarios.<\/p>\n<p>Product Introduction <br \/>This sensor is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port. Compatible with INMP441. Composed of a MEMS sensor, signal modulation, analog-to-digital converter, anti aliasing filter, power management, and industry standard 24 bit I2S interface. The I2S interface allows it to be directly connected to digital processors such as DSP and microcontrollers without the need for audio codecs used in the system. With high signal-to-noise ratio, it is an excellent choice for near-field applications. Having a flat broadband frequency response, resulting in high clarity of natural sound.<\/p>\n<p>Main performance: <br \/>Digital I2S interface with high-precision 24 bit data <br \/>High signal-to-noise ratio: 61 dBA <br \/>High sensitivity: -26 dBFS <br \/>Frequency response: Stable frequency response from 60 Hz to 15 kHz <br \/>Low power consumption: low current consumption of 1.4 mA <br \/>High PSR: -72 dBFS <br \/>It can be welded to the back panel for use, or directly used for surface mount welding <br \/>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. <br \/>Interface definition: <br \/>SCK: Serial Data Clock for I2S Interface <br \/>WS: Serial Data Word Selection for I2S Interface <br \/>L\/R: Left\/Right Channel Selection: <br \/>When set to low level, the microphone outputs a signal in the left channel of the I2S frame. <br \/>When set to high level, the microphone outputs a signal in the right channel. <br \/>SD: Serial data output of I2S interface <br \/>VDD: Input power supply, 1.6V to 3.6V <br \/>GND: Power Ground <br \/>Connecting with ESP32 development board: <br \/>This module &#8211; ESP32 development board <br \/>SCK &#8212; GPIO14 <br \/>SD &#8212; GPIO32 <br \/>WS &#8212; GPIO15 <br \/>L\/R &#8212; GND <br \/>GND &#8212; GND <br \/>VDD &#8212; VDD3.3<\/p>\n<p>Product list: <br \/>1X module <br \/>2X3pin pin arrangement (optional non welded pin arrangement\/welded pin arrangement)<img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S6faff5ae5b6d4c7ea2469ef80bf93746U.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S0def1bcad0fa4286a780243fa6c9ddbcU.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S56254c259d2d4e329cd3963d0c5d56115-1.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S7642b586bf25469c98648a2a4c571b60z-1.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-Sa16ada57c3364ce1988ae9cd5e75277dl.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S51ae85756a7b4f2daf3d63746c3a9c3bh.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-Sfd1f900b45f0418f94d6c3bfac6d2609e.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S591631dcc6cb411793991c832781b460n.jpg\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S350b4c6739b24b1bbb92e7616e651768E.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S0082a7b5932a4158a23249754b8bbf0d0.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S50f9dc90bed344308a204b12c6ecfe321.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S248bec5982f5420eb914e6cca8426d60B.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-Seaa9950adf31400a8b965364ea7d7d908.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S680683bf9ced49e7bccf6df5ce9ea0b8q-1.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S7b4ba9b15a79434d9e82e735ba516c40q-1.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S2eae86261d404587abc0034820d0757cY-1.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-Sc9c0b6aa8a4944e4abb7e173583d9bbbs.webp\" \/><img decoding=\"async\" class=\"wscnph\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S4fd2209405274c6f85e287c4a0ed0f97Q.webp\" \/><\/p>\n<\/div>\n<\/div>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Brand Name:&nbsp;diymore Origin:&nbsp;Mainland China High-concerned chemical:&nbsp;None Condition:&nbsp;New Type:&nbsp;Module is_customized:&nbsp;Yes Quantity:&nbsp;1 Application:&nbsp;Computer Package:&nbsp;SMD Choice:&nbsp;yes Features: 1.
