Hi AudioMoth design team (maybe @Andy, @Alex Rogers, Ruby, …), it is exciting to see that version v1.2 with its external microphone connector and ímproved mic / noise is now available!
Curious about the new mic part and what else might have changed with the circuit, I went looking for the updated design files in the usual places (https://github.com/OpenAcousticDevices, https://www.openacousticdevices.info/open-source, https://circuithub.com/projects/OpenAcoustics/AudioMoth/revisions/24499/board), but came up blank.
Are the design files for the new version v1.2 (and maybe also the µMoth) available anywhere (https://www.youtube.com/watch?v=bXkT8NP4zIs suggests they both still are open hardware designs)? If so, I would love to learn where to find them ;-)
Thanks in advance, and thanks so much again for your amazing work and this great project!
@Andy / @Alex Rogers It would be great if you could provide an update on this (or point towards someone who could). Thanks a lot! Pascal
Thanks for posting this question Pascal. I've been wondering about the frequency response of the new MEMS, especially in relation to high frequency bat signals. The external mic option presents a way to test that, compare with a calibrated mic. I'm listening forward to deploying ver 1.2 underwater with hydrophone input!
