USB host socket (85-32003-00X-1), I could not find any suppliers here. Where did you get that?[/quote]
Any USB host socket (type A) with two ports would fit.
We are actually thinking of going with SMD (no Arduino) directly combining PSU and Arduino/Pololu boards into a single board. Any volunteers on taking a first pass on that?
If someone does combine the boards, I would ask that external non-usb terminals be made available for +12v and +5v (off of the buck converter)… Just like it is today… these will be handy for future feature additions.
