Adafruit DS1307 Real Time Clock Breakout Board

Regular price $0.00 $15.57 Sale

Key Features:

  • DS1307 is the most popular RTC
  • Great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost
  • Works great with an Arduino using Adafruit's RTC library or with a Raspberry Pi
  • Perfect for datalogging, clock-building, time stamping, timers and alarms, etc.

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC - but it requires 5V power to work (although we've used it with 5V power and 3.3V logic successfully)

The DS1307 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day.
