usbSimStepper PCBs have arrived

I designed a dual stepper motor controller that interfaces to a computer via USB for use in my flight simulator. These boards will drive various instruments, such as my airspeed indicator. This is the first time I have used Seeed Studio for PCBs and I am very please so far with the end result. The total cost was right at $50 for 11 of these boards which measure about 3 inches square.

Here is one of the boards mostly populated with parts and installed on my home made airspeed indicator.



Update: There were a couple of minor errors on the board layout. Here is an updated schematic.
