Specifically, I would like to add the DS3231 RTC to an altimeter using a BMP180.  In fact, I would like to have an RTC in any device both to keep the time and display the time on any Backpack when it's not doing anything else.   This especially comes into focus with the Backpack V3, which provides a home for a DS3231 on the main PCB. same meat, different gravy. A DS3231 and HTU21D happily co-habiting. As already pointed out, each device has an address and will ignore traffic not for it's own address.
