The Adapteva website says these are "324-ball 15x15mm flip-chip BGA"
 but doesn't mention the pitch? Perhaps it's implicit — my
knowledge of BGA devices goes as far as appreciating that they are
difficult for hobbyists to work with. In any case, if it were 1mm or
higher it seems you could get a small four layer board done fairly
cheaply , and perhaps this could just do breakout and be used to
hook one up to an FPGA dev board. However, from a quick calculation it
looks like the pitch has to be 0.8mm or under.
Wondering if Omer, Sukkin, or Al have any ideas, as they've far more
experience with this sort of thing ...
As a last resort we could try the "quit whining and solder" technique :o)
