ds1307 RTC


I just bought the DS1307 Real Time Clock. I hava a question: I can not mount it on the top of my arduino, because I already have another sheild on it. I’d like to understand how to connet the pins…

  • if I well understood the two pins on the back of the board must be connected to analog ports 5-6. Is this correct?

  • how should I connect the 6 pins socket? It looks like it must be connected to ICSP port, but probably not all the pins are required. Do you know which pins should I connect to have it working?


the DS1307 use the IIC interface which is the A4 A5 of the Arduino pins.
and the 6 pins socket just supply GND and VCC pins for DS1307.
