I often don't drive for weeks or months at a time but would like to leave the v2 adapter plugged in.

What are the power consumption properties of the v2 adapter? Is it possible, while plugged in, to put the adapter into a sleep mode where it will consume very little power?

The onboard ATMega328p runs at 3.3v and it does not go into sleep mode. The STM32 and GPS can be put into sleep mode and waken up by ATMega328p.
