Thanks for the info @chipmc !

You have a specific part number or digikey link for the 400 uF cap you use. This is as simple as wiring the solar panel to VIN/VUSB pins and GND and then adding the cap between the same pins? I’m about to order another set of boards or at least pads for it and may add this.

In my application, the bulk of the time, the device wakes/sleeps every 5-20 minutes (just under the time where cellular renegotiation is required). It will occasionally sleep up to 4 hours. I also incorporated this Deep Reset into my PCB: Deep Reset Tutorial. @rickkas7, is the watchdog Timer just an alternative to the previous Deep Reset tutorial using a RTC instead of a GPIO pin or when would someone use this version over the prior? My guess is similar functionality but maybe a nicer by also having an RTC for deep sleeping?
