If I'm understanding the description of the CAD drawing of the Edison correctly, there would be ~0mm space between the Edison shield and an expansion board if you're using the 1.5mm expansion connector, ~0.5mm if using the 2.0mm connector, and ~1.5mm if using the 3.0mm header. That would mean that you really can't put anything on the board under the shield unless you're using a 3.0mm connector. Is that correct?
If so, does anyone have a source for the 3.0mm connector (in small quantities)? I'm not seeing it in stock anywhere...
