Looking to manufacture in a low resource setting, need help with files.

Hey people, I am looking to make some Audiomoth(s) or μmoth(s), but I am facing two issues:

The Knowles mic for the audiomoth 1.1.0 can not be found as it has become obsolete.
I can't find the BOM and Gerber data for the audiomoth 1.2.0 or for the μmoth.

Can someone please help find the data or suggest an alternative part for the mic, we are really trying to help our conservationists here.

Thank you!

I built some myself and just adapted the 1.1.0 so that it takes a knowles SPU0410LR05H element. Add and opamp with about 15:1 or 18:1 amplification and signals will roughly compare to the 1.0.0 version.
