AFAIK, emonSD doesn’t do anything that’s chipset dependent. i.e. the chipset shouldn’t be an issue.
If it were, there’d be a problem between Raspberry Pi versions, as the Pi2 and Pi3 chipsets are different.
This thread: Howto prepare a BananaPI R1 (BPI-R1) for EMONCMS, Freeboard and others shows it’s possible to use at least one other make of SBC to run an SD card based version of emonCMS on.
