Anyone had any experience with MEMS microphones. I've seen them at $0.03
I have seen some places say they have a simple output with a voltage bias already, e.g. around 0.8V.
But most things consider circuits to replace analogue microphones with capacitive coupling and a separate bias.
My thought is if the output is already DC biased, it could go directly to an ADC input on an ESP32, and need no other components to allow reading an audio input.
But data sheets seem unclear,

You should give a try to #boneconduction #audio
It could take like 3 months for your ears to adapt hearing coming both from vibration & sound, but afterwards you will not switch back!

I've been around here for a while without doing an #introduction post.
I'm #bisexual and have been married to my awesome wife for almost twenty years.
I was the father to a wonderful boy who had a profound #disability, he could not walk or talk, or even feed himself but he had the best laugh. He passed away in 2021 before his ninth birthday.

3ax accelerometer/gyro chip. Composite of 3 different chips that I decapped. Didn't get a complete view of top right unfortunately.
I thought the bottom was accel at first, but thinking they are gyros now? Dual mass vibrating kind? Lack of combs on the top devices is throwing me, just a few plates that I can see.
There are "pits" or cutouts under two of the three devices under the bottom, which is contributing to my feeling they are gyros (to help allow coriolis distortion)
