Adafruit DS3231 Precision RTC - STEMMA QT _MAKE_CABLE_JST Premium Digital Stainless Steel CalipersThe 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. We've had a breakout board version of this RTC for a while, but we want to make it even easier for folks to use, so now it comes with STEMMA QT connectors for plug and play simplicity. Most RTCs use an
