I'd like to suggest a 5v mems mic breakout board. I am trying to use one with a 5v pro mini and having to jump through hoops to get the signal amp'd up for better ATD resolution.

or

On the pro min's, break out the aRef pin. Because this isn't broken out, I am back to amping the mems mic.

I do not want to use the electret mic because of mic response considerations.

Thanks for your consideration.
