We would like to use the Audiomoth as a recording platform for adapting some ultrasound microphones to it (the Bufo or Myotis from our Sonitor system) to get low-noise recordings.

I would like to know whether in principle, it is possible to de-solder the built-in microphone (or install a switch, simply) to connect another microphone (like the Knowles SPU0410LR5H-QB or Vesper''s VM1000) to the PCB even though those microphones' native sensitivity would be much lower than the built-in microphone's, around -38 dB.

Are the pre-amps on the Audiomoth strong enough to boost the signal to an acceptable level? If it worked, we would be keen to show that the Audiomoth can be expanded with this open-source mic system. We would like to show that in an upcoming new version of our aforementioned article for which we would be glad to get new collaborators involved.
