Is possible to use the more accurate DS3231 instead the standard one with no code change??

Hi Stefano
Probably not.
the existing rtc in the design is around 5s per day, so even if not synced using NTP that is only around 35s per week.

I am not sure why the extra accuracy is needed though.

Any accuracy need is just cause I have 10 DS3231 in magazine :D

Hi Stefano
It actually should not be that difficult.
The code logic works to the best of my knowledge.

So if you are okay with programming the Arduino it should not take that long.
I would assume a simple library change and a few other changes it would go.
I do not have any DS3231 so am not in a position to test however.

No problem, I'll try, for what I read around,the only difference between the board is only the pps, I'll try and give you a feedback!

Thanks

Oneother things, in the pdf guide page 27 the title is "12V POWER CONNECTION FOR DRV8825 AND ULN2003 PCB" I Think is an error :)
