Am about to order an upgrade to my Raspberry Pi 2 to isolate the WiFi dongle from some drop-out issues I've been having on my PilotAware Classic. Although I suspect it's partly power supply issues. (Can't reallly justify a wholesale Rosetta upgrade).
However, I need to decide between Raspberry Pi 3B or 3B+ now that both work with the PilotAware software. I've found a supplier, but the latter seem to be in short supply with RS offering back-orders for Feb 2020!
Raspberry Pi 3B and 3B+ in comparison suggests power consumption is somewhat less on the 3B, with a few features missing/reduced. Much advantage of the older model for PilotAware?
