ICS-43434 I2S 33 MEMS microphone Module Breakout Low cost Low Pass Filter Mini-modulemodname=ckeditorDescriptionListen to the good news - we now hae a super small breakthrough board ICS43434 I2MEMS microphone. Just like "classic" element microphones, MEMS MIC can detect sound and conert it into oltage, but they are smaller and thinner. This microphone isn't een 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 aboe 24kHz.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 hae analog inputs, or maybe you want to aoid 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.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 drie the clock and word select pins at high frequencies and read data from the microphone. No analog conersion required!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 oltage to high oltage. No firmware or drier configuration is required, and you'll get 24-bit output instantly.This I2S MEMS microphone is bottom ported, so make sure you hae holes on the bottom, towards the sound you want to read. It's only the largest deice at 1.6-3.6, so it won't work with 5 logic (you're unlikely to use an I2S 5 logic deice anyway). Many beginner microcontroller boards don't hae 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).argumentSensitiity: 26 dB FS 1dBHigh performance mode SNR: 65dBALow power mode SNR: 64dBAHigh performance mode current consumption: 490ALow power mode Current consumption: 230AMike Wind Pressure Leel Oerload Point (AOP) : 120 dB SPLHigh performance mode sampling rate: 23 ~ 51.6kHzLow power mode sampling rate: 6.25 ~ 18.75 kHz
