Thanks to the\nintegrated 24-bit I2S interface, data transmission is completely digital,\nwhich keeps the audio signal resistant to electromagnetic scattered radiation\non the PCB. Developers appreciate this MEMS microphone for seamless\nintegration with voice assistants and low-noise audio tools. Versatile\napplication scenarios: This compact sensor board is ideal for acoustic room\nmonitoring, frequency analysis via FFT or for sound-reactive WLED light\ncontrols. As the microphone module has a 360 degree spherical characteristic,\nit picks up ambient sound evenly from any direction, allowing maximum\nflexibility in housing construction. FAQ: How to connect the INMP441\nmicrophone module to the ESP32? The connection is done directly via the I2S\npins without external codec. Connect SCK to GPIO14, SD to GPIO32 and WS to\nGPIO15. The power supply requires a stable voltage between 1.8V and 3.3V to\nVCC as well as connection to GND. How do I configure the left or right audio\nchannel? Channel allocation is controlled via the L\/R pin. When you set the\npin to GND (Low), the module outputs the audio data on the left channel. For\nthe right channel, connect the pin to VCC (High). What are the advantages of\ndigital output over analogue sensors? The digital I2S interface delivers an\nalready converted audio signal. This minimises signal loss on the leads and\nresults in noticeably cleaner voice reproduction with a minimum current draw\nof only 1.4 mA.

While traditional signal paths are often susceptible to electromagnetic interference on the motherboard, this microphone module forwards a pure digital signal to your controller. Developers block the dreaded background noise already at the hardware level. You will feel the relief when your oscilloscope displays a stable, clean signal line and the software instantly processes your voice commands precisely without misinterpretations.\u003c\/li\u003e\n         \u003cli\u003eFAST ESP32 INTEGRATION Stop losing valuable development time with incomplete pin assignments. The clearly defined connectors for SCK, WS and SD allow direct connection to ESP32 and Arduino architectures without additional audio codecs. The L R pin allows flexible control of the channels for stereo arrangements through simple high or low levels. The module supports smooth implementation in modern smart home centres or WLED lighting projects. You plug in the board, load the I2S sample code and see your project running immediately without errors.\u003c\/li\u003e\n         \u003cli\u003ePRECISE AUDIO RECORDING Experience acoustic clarity with true 360 degree ball characteristics. With a signal-to-noise ratio of 61 dBA and a sensitivity of -26 dBFS, the sensor captures the ambient sound in the room absolutely evenly. The flat broadband frequency response from 60Hz to 15kHz maps human speech amazingly naturally. Whether for IoT audio devices, voice assistants or frequency analysis, this sensor module provides your digital signal processor with exactly the detailed audio data necessary for reliable speech recognition at a high level.\u003c\/li\u003e\n         \u003cli\u003eEFFICIENT POWER CONSUMPTION Protect the energy reserves of your mobile prototypes and battery-powered IoT systems. When fully operated, the compact component draws only 1.4 mA current at -75 dBFS PSR. This minimal power draw drastically extends the life of your battery projects without compromising on audio quality. Engineers appreciate this thermal and energetic efficiency as it allows for more compact chassis designs and noticeably increases the reliability of the overall system during continuous operation.\u003c\/li\u003e\n         \u003cli\u003eCOMPACT INSTALLATION SIZE This listing contains 3 pieces of the precisely manufactured INMP441 module, ideal for the tailor-made expansion of your existing hardware setups or for targeted individual tests. Each module leaves production after strict quality controls and reaches you in protected packaging. The minimal footprint makes it easy to lay the cables neatly on the breadboard or the final integration into custom enclosures, giving your prototype a clean and industrial appearance. Start your next audio project now without risk.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Ruvan","offers":[{"title":"Default Title","offer_id":44375103733940,"sku":"de-B0H4MCZZ1R","price":113.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/de-B0H4MCZZ1R.jpg?v=1788272530","url":"https:\/\/auspowers.com\/products\/ruvan-inmp441-low-noise-i2s-microphone-module-for-esp32-24-bit-omnidirectional-mems-microphone-board-360-degree-audio-recording-sensor-for-arduino-smart-home-development-3-pieces","provider":"AusPower Australia","version":"1.0","type":"link"}
