"On AudioMoth 2 we're going to use two AA batteries and a 3.3V voltage booster IC to increase the battery voltage up to 3.3V. This is a bit less efficient than a voltage regulator but you win that loss back by being able to drain the batteries completely and access their full capacity. It also makes the device a bit smaller and cheaper to deploy. The newer processor also uses significantly less power."
Is this still been planned? Is so, are there any thoughts on the timeline for this new design? Will AM2 be with us for the start of the survey season next year, Spring 2020? Or perhaps should we plan on the 2021 season?
PS - Loving the Round 7 devices that turned up this week! Keep up the good work!
