ICS-43434 I2S 33V MEMS microphone Module Breakout Low cost Low Pass Filter Mini-module _x000D_ _x000D_ modname=ckeditor_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ Description _x000D_ Listen to the good news - we now have a super small breakthrough board ICS43434 I2MEMS microphone. Just like "classic" element microphones, MEMS MIC can detect sound and convert it into voltage, but they are smaller and thinner. This microphone isn't even analog, it's purely digital. The I2S is a small, low-cost MEMS MIC with a range of about 50Hz-15kHz, suitable for all general purpose audio recording/detection. The chip has a built-in low-pass filter that cuts the frequency above 24kHz. _x000D_ For many microcontrollers, adding audio input is easy with one of our analog microphone breakthroughs. But as you get to bigger and better microcontrollers and microcomputers, you'll find that you don't always have analog inputs, or maybe you want to avoid the noise that seeps in with analog microphone systems. Once past the 8-bit micros, you'll usually find that I2 can take the peripheral digital audio data in! That's where the I2S microphone breaks through the featured TDK ICS43434 in. _x000D_ Instead of the analog output, there are three digital pins: clock, Data, and Left/Right (Word Select) clock. When connected to a microcontroller/computer, the "I2S controller" will drive the clock and word select pins at high frequencies and read data from the microphone. No analog conversion required! _x000D_ A microphone is a single unit element. You can Select the Select Pin on the left or right channel by connecting it to power or ground. If you need stereo sound, pick up two microphones! You can set them to stereo by sharing the clock, WS, and data lines, but with the one with the choice ground, a person with the choice can choose high voltage to high voltage. No firmware or driver configuration is required, and you'll get 24-bit output instantly. _x000D_ This I2S MEMS microphone is bottom ported, so make sure you have holes on the bottom, towards the sound you want to read. It's only the largest device at 1.6-3.6V, so it won't work with 5V logic (you're unlikely to use an I2S 5V logic device anyway). Many beginner microcontroller boards don't have i2, so make sure it's a supported interface before trying to put it all together! The microphone is best used with cortical M-series chips such as SAMD21 or SAMD51, ESP32, RP2040 or RP2350, or RASPBERRY PI (e.g. Raspberry Pi). _x000D_ argument _x000D_ Sensitivity: 26 dB FS 1dB _x000D_ High performance mode SNR: 65dBA _x000D_ Low power mode SNR: 64dBA _x000D_ High performance mode current consumption: 490A _x000D_ Low power mode Current consumption: 230A _x000D_ Mike Wind Pressure Level Overload Point (AOP) : 120 dB SPL _x000D_ High performance mode sampling rate: 23 ~ 51.6kHz _x000D_ Low power mode sampling rate: 6.25 ~ 18.75 kHz _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
