I am thinking of replacing NANO with Uno.
Do you think this will cause a lot of changes in code or components ?
The number of I/O's brought out to the headers are different.

Nano claims 20 digital (6 PWM) and 8 analog. I only see pins for 14 digital; like Uno.

2k of the 32k FLASH used for bootloader.

Uno has 14 digital (6 PWM) and 6 analog.

0.5k of the 32k FLASH used for bootloader.

Maybe, but not without a lot of work. I have several concerns...
1) it’s from Banggood
2) the library is from a private individual; not from an Arduino sponsored source
3) there is at least one reviewer who says the library does not work as expected
4) with a Nano, the supplied headers will not work as designed, requiring custom direct wiring. This is a chance for errors.
5) there are many DS1307 Arduino compatible boards available, that would be better choices.

Tnx for your replay!

Will any of these be a better option?
