I wanted my uconsole CM5 have RTC, but buying AIO V2 just for using RTC module only wouldn’t be a good usage of resources. So it was hard to choose between normal expansion and AIO V2.
But today, when I read the store page of upgrade kit, I found out that carrier board of upgrade kit has a port for “RTC battery for CM5”. So I googled about it, and CM5 had their own RTC! And I immediately chose the standard one with NVME battery board and purchased the kit.
So, if I’m using CM5, am I good to go with some RTC battery?
