The new AudioMoth 1.2.0 with firmware version 1.5.0 on-wards can be adapted to be compatible with external electret condenser mono microphones, commonly known as plug-in powered (PIP) microphones.
To adapt the hardware, you'll need the 3.5 mm jack socket (SJ2-35464A-SMT-TR), which can be soldered to the exposed pads on the front AudioMoth surface.
The 3.5 mm jack socket can be sourced from a number of suppliers here.
PIP microphone assemblies are available, such as the Primo EM258 or they can be built from components. AudioMoth 1.2.0 can be used with a wide variety of differently wired 3.5 mm jack plugs. To find out more, read our full application note on using AudioMoth with external microphones here.
