Real Time Blue Clock module DS3231SN ChronoDot V2.0 I2C Diameter 3CM
THIS IS THE LATEST VERSION 2.1
The ChronoDot RTC is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC (TCXO). It includes a CR1632 battery, which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required.
The top side of the Chronodot now features a battery holder for 16mm 3V lithium coin cells. It pairs particularly well with CR1632 batteries.
The DS3231 has an internal crystal and a switched bank of tuning
capacitors. The temperature of the crystal is continously
monitored, and the capacitors are adjusted to maintain a stable
frequency. Other RTC solutions may drift minutes per month,
especially in extreme temperature ranges...the ChronoDot will drift
less than a minute per year. This makes the ChronoDot very well
suited for time critical applications that cannot be regularly
synchronized to an external clock.
The ChronoDot will plug into a standard solderless breadboard and also has mounting holes for chassis installation.
The I2C interface is very straightforward and virtually identical to the register addresses of the popular DS1337 and DS1307 RTCs, which means that existing code for the Ard, Basic Stamp, Cubloc, and other controllers should work with no modification. This new version has a battery holder, no soldering required!
