Are microcomputers based on AR9331 needed?

Question

Do it yourself

which time I expose the microcomputer on Avito. However, the number of views is very low. The suspicion creeps in that or somewhere cheaper (which of course can be).
roofing felts, everyone who needs it has already typed Black Swift on the kickstarter.
or maybe this is a dead end branch and such microcomputers are simply unnecessary to anyone?

Answer 1

on Avito? no wonder, not the same contingent

Answer 2

how much?
