Adafruit DS3231 Precision RTC Breakout Compatible With_Raspberry Pi 3 that can natively support suchThe DS3231 Precision RTC Breakout delivers highly accurate timekeeping with built in temperature compensation and battery backupperfect for clocks, data logging, and projects that need reliable time even without power. The datasheet for the Adafruit DS3231 explains that this part is an "Extremely Accurate IC Integrated RTC TCXO Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a
