Adafruit DS3231 Precision RTC Breakout Shipping:4-6 Days Stereo line out - HeadphonesThe datasheet for the 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 small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that's all well and good, but those crystals have slight drift, particularly when the temperature
