One my my upcoming dash projects is going to involve 6 total gauges, across 5 displays.
I’d like to use something a little less expensive than a pi5 for the 4 ancillary gauges. Would a pi zero 2w be capable of running at max 2 low speed gauges on a 3" display? could I run the two main gauges on the pi5 and use data multicast to 4 pi zeros for the others? Alternatively what about possibly using a USB 3.0 hub and USB to hdmi video cards?
