Pretty neat.

Though, with these ever smaller versions, and the RP2040 having a very modest processor and modest quantity of RAM (relative to the other Pi boards, etc) . . well, what is the power consumption on these?

Are they low enough in power consumption that they can run on, say, AA batteries for weeks? Months?

Or is building long-term-use battery operated devices from these still not yet feasible?
