Adafruit Precision Real Time Clock (RTC) FeatherWing
FeatherWings add specific functionality to your Feather development board. They fit directly on top of your Feather using stacking header pins.
The DS3231 Precision RTC FeatherWing adds an accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather board. This RTC is the most precise you can get in a small, low-power package.
Most RTCs use an external 32 kHz timing crystal to keep time with low current draw but these have slight drift, particularly with temperature changes. This DS3231 has a crystal inside the chip and a temperature sensor compensates for the frequency changes by adding or removing clock ticks.
A CR1220 12 mm coin cell battery holder enables battery backup to keep time even without main power. A CR1220 battery is not supplied (RS 866-0653).
