• Hi Gordon,

    Thanks for explaining it in detail! That's a bummer (for me in this particular application), but understandable.

    Perhaps a MDBT42Q could be an alternative (as i assume that one does not have to swap and should be accurate), but i have no spares laying around.

    I'll then use a Pico without the Crystal and a DS3231 module as an external reference. I've tested that in the meantime and seems to be a working 'alternative'.
