Hi Rick,<br>
<br>
I will send out some pictures for you.<br>
<br>
Keep in mind that the connector placements, board sizes and even the
pin-outs are preliminary. We need to build the first units as a set,
and things might need to be tweaked to accommodate routing or parts
placement.<br>
<br>
My model is just the first stab at a system mechanical build.<br>
