Hi guysss. I'm a noob and new here with lil knowledge on electronics and Arduino. I'm willing to search and learn if it's something I don't know and will help me.

I'm working on a proposal project about digital stethoscope. And I was advised to use a microphone which supports I2S, I was originally planning to use Electret Microphone MAX4466, but I decided to use MEMS microphone as it support I2S.

I found two candidates for my project which is:
1. SparkFun MEMS Microphone Breakout - INMP401 (ADMP401)-https://www.sparkfun.com/products/9868
2. Adafruit Silicon MEMS Microphone Breakout - SPW2430 - https://www.adafruit.com/product/2716

Which microphone is better? If you have better microphone suggestion, I'll listen and why I should choose them.

Thank you

MarkT

What do you need from your microphone in terms of sensitivity and noise performance?  That's the
first thing to research.  MEMS devices seem to be a lot noisier than good microphones, note, at around
30--40dB noise floor.

I've no idea if that's a problem, research is needed.

You may have to experiment.

Neither of your links is an I2S microphone.

MEMS does not mean I2S.
