From the project
low-cost marine acoustic recorder
Actual preferred firmware verson is adalogger_V3
Of importance is a GUI (LCMare.py) that provides access to basic operations, like inspecting LCmare file parameters, visualizing time series and spectra, to configure the firmware, to convert compressed to wav files, and to upload latest firmware
