== '''1.Description''' ==
<br>
Loads of projects require accurate timekeeping. Whether you're building the ultimate alarm clock or making a custom datalogger, keeping accurate time is easy and safe with our Real Time Clock (RTC). Unlike most RTC modules, this one is backed up by a supercapacitor instead of a lithium battery - making it safer for use indoor. When connected to power, the RTC trickle-charges the supercap in just a few minutes - enough to keep the clock going for a couple of weeks once power is removed. The onboard RV-3028 handles timekeeping and date with 1ppm accuracy and has an incredibly low power consumption (45nA at 3V).
