RV3028 Real-Time Clock (RTC) Breakout

An ultra-low-power ( ~100 nA), highly accurate real-time clock breakout. The RV3028 RTC breakout is perfect for adding timekeeping to your project and, thanks to the tiny onboard battery, it’ll keep time when your device is powered off. Like all the best timepieces, it’s Swiss-made! The RV3028 RTC is factory-calibrated and is quoted to drift by just ±1 second per million seconds at 25 degrees. This will vary slightly depending on a number of factors. In testing, its performance is better than ±2 seconds per million seconds. For comparison, that’s up to five times more accurate than your average digital watch.
