    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>
