RAK7243C with RTC?

Hi, is it possible to use an RTC with the RAK7243C? I have a project where the RAK7243C may need to run offline for a few days, so I would like to use an RTC to ensure that the time does not go out of sync.

Hi @clearfin,

Yes, it is possible to use an extra RTC with RAK7243C, but you need to do some configuration or make a application in RPi software to obtain the correct time from the extra RTC.
