Has anyone added an RTC real time clock, the battery powered system clock, to a Raspad? Adafruit has a lil board for this, but I'm interested in hearing other options. Perhaps someone has a homebrew design?
I'm mostly offline, so thought to deploy timekeeping via a personal time signal server or from my gps Bluetooth, but this seems a more elegant option.
