How long does raspberry pico run on CR2032? I'm asking because used Arduino ide to program STM32L011 and it would run for months or even years.

- DrewADesign 10mo agoI believe you need 5v to run the regular $4 pi pico board. The chip only requires 3.2v though so maybe it’s not a hard requirement? There are probably other lighter weight RP2040 boards but I don’t think months or years-long low power usage was an intended goal— it’s $4 (still!) with 40 GPIO pins and PIO and it runs micropython for people scared of/chafed by C— it’s a prototyping/hobby tool.
- galleywest200 10mo agoPi Pico has a lower power mode that sleeps when not in use that draws well under 5v, but you the programmer have to activate it. I think it is called “lightsleep” but may be wrong.
- DrewADesign 10mo agoHuh, interesting. I haven’t played around with one in a few years.
- 05 10mo agoIt has sleep current of 200microamps, so no longer than 40 days…
- bigfishrunning 10mo agoThe STM32L011 in no way requires the arduino IDE; your code would likely compile with GCC just fine. The pico would probably work if you redesigned your project, but your hardware very likely doesn't need to change, just the software you're using.
