RTC module - Easypic5

[ardhuru]

You can use this with pretty much any pin that I2CWrite/I2CRead work on, and
you can probably find several PBP examples here for working with the DS1307.

True, especially since you're using a complete module. If you were using a plain RTC chip, I'd suggest choosing 2 pins which are weak pull-up capable, the'd save you 2 external resistors on the signal lines.
