DS1307 RTC Module - Real Time Clock Module

DS1307 RTC Module - Real Time Clock Module

This is an excellent battery backed real time clock (RTC) that allows you to track its time even if the microcontroller has been reprogrammed into your project or if power is lost. The DS1307 is the most popular RTC - but it requires 5V power (although we have successfully used it with 5V power and 3.3V logic), data logging, clock generation, time stamping, timers and alarms, etc.

• Works perfectly with an Arduino using the RTC library or a Raspberry Pi (etc single board linux computer).
• Including PCB and header
• Plug in any breadboard or use wiring
• Two mounting holes
• Can hold 5 years or more

DS1307 is simple and inexpensive, but it is not a high precision device. You can lose or win up to 2 seconds a day. For a high precision, temperature-compensated alternative, pleaseDS3231check precision RTC.
