hah. Yea I think perhaps I was a bit hot on those estimates. Its neat vendors practically give away some of these eval kits for marketing (which is almost certainly what this is, guised under a charity...), but it makes life awfully hard for me when clients now expect their 5000 unit run ARMx single board computer should cost about 15$ a pop (totally unachievable) plus engineering. I still hold on to my conclusions.
Without breaking down everything piece by piece, we spend about 3.00$ in plastic and other headers on a medium qty design that looks about comparable to what theyre doing (i/o wise). Also, female 1/10" headers are quite a bit more expensive than male, which I think skewed my intuition a bit.
