Description

A Feather board without ambition is a Feather board without
FeatherWings!

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.

This RTC is the most precise you can get in a small, low power
package. Using our Feather Stacking Headers or Feather Female Headers
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 very 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.

With a CR1220 12mm coin cell plugged into the top of the FeatherWing,
you can get years of precision timekeeping, even when main power is
lost. Great for datalogging and clocks, or anything where you need to
really know the time.

A CR1220 coin cell is required to use the battery-backup capabilities!
We don't include one by default, but we do stock them so pick one up
or use any CR1220 you have handy.
