Verdict
Firefly ROC-RK3588S-PC
7.5 / 10 Expert Rating
The original RK3588S design, still notable for UEFI boot support that makes standard Linux installs far easier.
Radxa CM3
7 / 10 Expert Rating
A pragmatic supply-chain hedge for CM4-based products, not a board for hobbyist tinkering out of the box.
