Hi all, total newbie here with what may well turn out to be a stupid query:
So I'm looking to find a way to give my pi a kind of ups system to enable safe shutdown on power loss and also to cover any momentary losses of power (switching batteries, starting engine etc). I've come across this https://www.aliexpress.com/item/33011106...dBgRG&mp=1 little board on Aliexpress that takes 2 18650 batteries and claims to do what I need (I think). My main question is with regards to the GPIO connection. I think I'm right in saying that it looks like this would connect to the I2C pins (as well as 5v and ground of course). With I2C being a bus I am thinking this would mean it can communicate over that bus without stopping me adding sensor onto it in future?
I know there have been a few questions about this in the past, sorry if I'm retreading old ground but I couldn't find a definitive answer. As for why I'm not using a pijuice, its almost the same price as the pi itself. surely there must be a cheaper solution, right?
Thanks in advance for all the help, and again, I'm a total newbie at pi's communication and any kind of programming so kid gloves and explaining as if to a total idiot is appreciated
