## Description

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 the **Makerverse™ Real Time Clock (RTC)**. Unlike most RTC modules, this one is backed up by a supercapacitor instead of a lithium coin cell - making it safer for use in the classroom. 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).

- Safer for classroom use - no lithium battery
- Tracks year, month, day, weekday, hour, minutes, seconds
- Supercapacitor backed - keeps time for two weeks after power is removed
- Automatically switches between main power and backup power
- High accuracy clock - loses about 30 seconds per year

**Makerverse Overview**

 **Makerverse** hardware is designed for makers, by makers. We're making the tools and modules we think are the most useful to electronics enthusiasts and people that just want to get their projects done. As experienced makers ourselves, we're building in the features and design considerations that we find most valuable and have wished for in other modules.

All Makerverse devices are [![](https://core-electronics.com.au/media/wysiwyg/product_images/Core-Electronics-Original.png)](https://core-electronics.com.au/original) products designed by our team in Newcastle Australia. We manufacture the modules here as well.
