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.
