Thanks for that link....nice overview.

Emil - AudioMoth open sourced all of the design, in case you would like to have them built on your own. The price increases to about $77 for qty 50, instead of the larger orders with GroupGets. The downside is you would have to do the board testing yourself and a few of the components (per circuithub) are not in stock. Those shouldn't be difficult to overcome; however, if you wanted them by mid-November you would need to do this soon to allow time for testing. On additional note....I believe one of the AudioMoth team members mentioned that a part was being changed out (EOL'd or maybe just unavailable) and I don't know if they has been fixed in the latest BOM and schematics. Maybe one of the team members can comment here...in case I have any of this wrong :) Best, Robert
