How many miliseconds is needed not to shut down on UpSquared?
I am using UpSquared in an embedded project. In my project, I have a main battery to power UpSquared. I also have a back-up battery for some situations.
For example, my main battery is not able to power my UpSquare anymore and need to switch back-up battery. My question is that how many minimum miliseconds are needed to switch time because I dont want my UpSquared to shut down.
