@sb what do you intend it for, if I might ask?

I work on a IoT management solution.

Not exactly robots, smart homes etc.

If you take this path (node, clojurescript) you should be aware that some node packages might not cross-compile out of the box. I had an issue with child_process, for example. I tried to link with host libraries. Although it was an exception, other dependencies were built smoothly

have you looked at olimex boards too ?

they have some pretty nice ones (better i/o than rpi and even native sata ... )

they are using the same allwinner cpu that pine64 folks do

https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/open-source-hardware have a look around ... they have something on the a64 cpu too
