Adafruit Datalogger - and RTC
I just received the Adafruit Datalogger shield. Unfortunately, I also need to use a DS3231 RTC both for stability and the interrupts. There seems to be a conflict between the Datalogger RTC chip and the DS3231. Is there an easy/safe way to disable the RTC? Can I just cut the traces between the SDA/SCL pads and A4/A5? - or will that have some other consequences?

Re: Adafruit Datalogger - and RTC
Yeah, both chips use the same I2C address.
Cutting the traces is probably the best idea, between the A4/A5 pins and the two holes labeled SDA/SCL. That will leave the pull-up resistors connected to the DS1307's I2C pins, so the chip will see a valid but inactive bus.
