USB servo board first PCB prototype

After a few weeks away, it was nice to get back to Nerd Towers and start etching stuff and messing about with copper boards and solder again.
After lots of development and testing on breadboards, it's finally time to try the usb servo board out for real - here's the first set of etched PCBs for the controller.

We've tried to keep the board as compact as possible, but still allow room for an 8-pin DIP (or one of our spanky new SMT-to-DIP boards) as well as all 20 servo channels.

Phew! That's a lot of holes to drill with a hand-operated push-drill!

How the controller board looks, from the "business side".
