AudioMoth GPS Hat (Group Order - Round 4)

 AudioMoth GPS Hat is a GPS receiver that can be used to set the time and improve the clock accuracy of AudioMoth. It is compatible with AudioMoth 1.1 and 1.2, and it is soldered directly to the exposed GPIO pads. It is the same electronic design as the AudioMoth GPS Board used with AudioMoth Dev but in a different form factor. The standard AudioMoth firmware supports GPS for updating the real-time clock, and measuring the precise sample rate, before each recording period. This allows events within a recording to be assigned a timestamp that is accurate to within a few milliseconds with little increase in overall energy consumption.  In many applications, this level of time synchronization is sufficient. However, sometimes more precise time synchronization is required. For example, when the source of acoustic events must be localized to high accuracy. In these settings, the alternative AudioMoth GPS Sync firmware can be used. This solution continuously powers the GPS whilst recording.
