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).

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
