opensats supports krux?

funding via zaps, crowed funded, much better than foundational.

is the rockpro a better alternative or is it not possible on an sbc?

I don't know it. Raspberry Pi is a unique fantastic, it is not the point. Just, it does not replace a computer anymore. I run my bitcoin node and monero node on a intel nuc. More sure to be stable with that. Raspberry pi is a no-coiner machine for run a node or anything related crypto, isn't it? Almost wast of money in some cases.
