RTC real-time clock module DS3231SN ChronoDot V2.0 I2C
Oporating Voltage 5.0 V DC.
Battery type required CR1220 battery
The DS3231 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continuously 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 address, which means that existing code for the Arduino, Basic Stamp, Cubloc, and other controllers should work with no modification.

Description
This module features the adjustable LM2596 step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation.
This module has a multi-turn trimpot (potentiometer) that you can use to adjust the LM2596's output voltage. Since the trimpot has 25 turns of adjustment you can easily adjust the output of the module to exactly the voltage you need.
The simplest way to reduce the voltage of a DC supply voltage is to use a linear voltage regulator (LDO), but linear regulators step down voltage by dissipating the excess energy as heat and do not yield any current step up. on the other hand, can be remarkably efficient and provide a step up in current output. Buck converters are one of the best ways to provide a regulated voltage from a battery since they don't waste near as much energy in the process of dropping the input voltage as a linear regulator would waste.
