I connected the DS 3231 clock.
RTClib library.
Error: RTC lost power, lets set the time!
I changed several Due boards.
I changed several boards DS3231.
I tried 3.3v and 5v through a 3.3v power converter.
The time and date are not set accordingly and the clock does not go.

Thoughts:
1. There is a CR2032 battery, not a lir2032 battery. Maybe this is the problem? Without a battery, the same error.
2. Can it be submitted directly 5v? Will the I2C port burn out?

The problem is resolved.
The library has interface 1 (70-71pin), not 0 (20 and 21)
