Beschreibung

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)

Works great with an Arduino using our RTC library or with a Raspberry Pi (or similar single board linux computer)

  • PCB & header are included
  • Plugs into any breadboard, or you can use wires
  • Two mounting holes
  • Will keep time for 5 years or more

Note: This product does not come with a CR1220 coin cell battery. We recommend you purchase a coin cell battery to use with this product.

The DS1307 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day. For a high-precision, temperature compensated alternative, please check out the DS3231 precision RTC. If you do not need a DS1307, or you need a 3.3V-power/logic capable RTC please check out our affordable PCF8523 RTC breakout

Check out our detailed guide for wiring diagrams, schematics, fritzing objects, library code and more!

5 von 5 vollkommen ausreichend

einen Akku rein und angesteckt (habe Kabel angelötet) zu einem Raspi mit Montageband ins Gehäuse geklebt und nun als Multimediastation im Aussendienst im Einsatz. Nicht immer kann man den Raspi mit dem WLAN verbinden - aber meiner hat immer die richtige Zeit
