I will start testing very soon with an AudioMoth Dev unit to record signals from tiny ground arthropods. The signals are very weak and very low frequency (some audible, some not), so I will need to preamp them by a factor of 100 (+40dB) or 1000 (+60dB). I will use a shielded 10 µΩ piezoelectric film as a sensor - https://www.te.com/usa-en/product-CAT-PFS0010.html. Andy provided very valuable information about the device gain values in https://www.openacousticdevices.info/support/device-support/calibration-for-sound-pressure-level-measurement/p-1/dl-60800bbcbb7c0c001500dc98. However, I don't know if it is possible to modify the firmware on the device or if there would be any complementary software or hardware solution for me to achieve the goal. Thanks in anticipation for your help and support.

As noted in a previous post (https://www.openacousticdevices.info/support/device-support/where-i-can-buy-the-mini-jack-socket?origin=auto_suggest), the recommended 3.5 mm audio jack connector from CUI Devices (model SJ2-35464A-SMT-TR) has seemed to be a very difficult device to be ordered immediately in very small quantities - since I don't have that many AudioMoth 1.2.0 units - even within the US, but I could be wrong. Does anyone know of any manufacturer that produces a similarly designed connector (6-pin right angle surface mount)?
