I both agree and disagree with this sentiment. One of the reasons I would
like to have six servo outputs, is that I've got a Lynxmotion arm that I want
to control. The arm comes with a Scott Edwards serial servo controller.
The problem is that a robotics arm has a "path" not a "postion". So to move
from point a to point b, I'd really like to move through several inbetween points
i1, i2, i3, and i4. However, since the SSC board only runs at 2400 baud (or
4800) the command to position 6 servos requires many ascii characters and
the first servo starts moving before the next ones are in place. All in all it
makes for an extremely jerky arm. (Needless to say I'm writing new software
for the SSC board :-)
However, like Sean, having a serial port (or two) on the expansion board would
be useful. There is only so much room though.

Having a synchronous serial port would be too good to be true, but I can do most of what I need with just one more async port over what the Handyboard currently has. Haven't (...)
