Probably see SBC's used more as a term for them than SoC's as they incorporate more than just the die (imho)

Well, except once you have a PCIe daughter card it's no longer an SBC; you have at least two boards right there.

[_joel]

No but it is before you add one, so that's the best place to start.

[monocasa]

Not necessarily. If this is based on a CM4 (almost certainly), then there's no SBC at all since the CM4 is a SoM.

[_joel]

Yes and there are dozens more than just the CM4 that have it embedded... on a single system board.
