1.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 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).


2.Parameters


Accuracy: ±1ppm @ 25°C Working Temperature: -10°C ~ +50°C Dimensions: 22.5 x 24 mm Positioning Holes: 2 x M3, spacing 18.923 mm Weight: 3.5 g


3.Features


  • Safer for indoor 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
