Hi, Do the jack sockets for AudioMoth 1.2.0 need to be model SJ2-35464A-SMT-TR or can 4 pole alternatives (like in this pdf) be used. Thanks

Connect the 'TIP' to either 'L signal' pad and 'SLEEVE' to either 'ground' pad. This will connect the microphone but the AudioMoth won't know that it is there. To tell the AudioMoth that an external microphone is present make a direct connection between the 'jack detect' pad and either of the two 'ground' pads.

@Alex Rogers Thank you so much! So, it would be something like that?

In this case, could I use also the mens mic this way when not external mic connected or it would be disbaled permanetly?

Please, could someone confirm if this alternative connection will work before I make a mess? ;)

If onboard mens mic is going to be disabled permanetly maybe it is better to bypass the connector and make the external mic conection directly to the board. What do you think?

Thanks in advance for your help

Check the layout of the microphone pads in the application note here: https://github.com/OpenAcousticDevices/Application-Notes/tree/master/Using_AudioMoth_with_External_Electret_Condenser_Microphones Connect the + pin of the microphone to either of the 'L signal' pads and the - pin of the microphone to either of the 'ground' pads. Then also connect 'jack detect' to ground to tell the AudioMoth that an external microphone is present.

Great. Let´s try. Thanks!

Done! It works fine at home. Let´s see how it sounds in the field. Thanks again Alex.

Thanks Seth! In the end I got a colleague to help and he did exactly that, though he glued it to the top surface rather than the side. A good solution and works fine :-)

Thanks Alex for your helpful reply!
