Description

A Feather card without ambition, it's a Feather without FeatherWing card! The Precision DS3231 RTC FeatherWing will add an integrated RTC ultra precise with temperature compensation on any card Feather. 

By using the stacking connectors for Feather or the female connectors for FeatherYou can easily connect this FeatherWing Feather card and take flight.

The DS3231 circuit documentation explains that this component is circuit RTS I2C extremely accurate, and it's true. This the most accurate Real Time Clock (RTC) ets circuit that we saw and small with low consumption.

Most of the RTC circuit uses an external quartz 32 kHz to conserve time. But these quartz have the unfortunate tendnace to deviate at the time, mainly when the temperature changes. Temperature plays directly on the quartz oscillation frequency. This circuit so integrates quartz in his case but also a temperature sensor to correct the change of quartz oscillation.

Sold without battery CR1220.
