Listen to this good news - we now have a breakout board for a super tiny ICS43434 I2S MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This microphone doesn't even have analog out, it's purely digital. The I2S is a small, low-cost MEMS mic with a range of about 50Hz - 15KHz, good for all general audio recording/detection. The chip has a built in low-pass filter that cuts frequencies above 24KHz. https://elecena.pl/product/26960164/adafruit-i2s-mems-microphone-breakout-ics-43434 2024-09-26 https://elecena.pl/product/26960164/adafruit-i2s-mems-microphone-breakout-ics-43434 2026-06-26
