DS3231 Precision RTC FeatherWing - RTC Add-on for Feather Board

3028 - DS3231 Precision RTC FeatherWing - RTC Add-on for Feather Board

Adafruit Industries LLC

This is the DS3231 Precision RTC FeatherWing it adds an extremely accurate I²C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. Using a Feather Stacking Header or Feather Female Header you can connect a FeatherWing on top of your Feather board and let the board take flight. 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 changes (the temperature changes the oscillation frequency very slightly but it does add up) This RTC is in a beefy package because the crystal is inside the chip! And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule.
