Yeah...It's also a waste of power and time. ;)
I really don't know. Once I got mine I
became far, far less excited. Now
it's just been relegated to running on the UPS doing nothing but serving a MOP
image for a DECserver.
I'm afraid these things could give a whole crop of kids totally the wrong
idea about what embedded programming is. Using a familiar platform is neat
because it means you can start from knowledge you already have but running a
full-blown timesharing OS just to control a few blinkenlights or whatever is
morally wrong.
There are other cheap SBCs that are a better fit to
simple things, and anyway
thanks to oshpark.com (and until recently batchpcb.com -- but at this point,
good riddance!) etc. it's really not so expensive to make small custom PCBs
any more. Saving the wiring/effort it would have taken to adapt the SBC to
your application is worth *something* so the custom route may not even cost
extra.
Going the custom route is more educational, too. ;)
