Hi,

Yes, connect the 'jack detect' pad to the adjacent 'ground' pad with a small jumper so that the AudioMoth knows that the microphone is there. Then, connect pin 1 of your jack, which is the 'sleeve', to one of the 'ground' pads, and pin 2 of your jack, which is the 'tip', to either of the 'L signal' pads. You don't need to connect pin 5.

The correct socket is available from GroupGets:

What microphone are you planning on using?
