It's not a full Arduino: I could not manage to get below ~ 40 mA with my Uno, whereas the bare ATmega in SLEEP_MODE_PWR_SAVE, with only the async timer active, took something like 2 µA.

I expected a sleeping Arduino and an Alkaline battery pack could be a "set-it-and-forget-it" system but without calculating out the energy consumption, I didn't guess it would perform that well. So, @DirkPitt, there's some real-world support data. | |
