Remote Battery Voltage Monitoring
I've got my Kiwi setup at a remote location and was wondering if there was an inexpensive way to monitor the battery voltage which is currently charged via solar. I know there are out of the box solutions for this as I used work in the cellular industry but those boxes were quite expensive for what I need. Unfortunately, my solar controller doesn't have this ability.
I saw a video online where you can read voltage from the BBB but I'm unsure if I can use those pins because of the daughter board location.
Does anyone have a similar setup that could offer any advice?
