None at all. I want the board to be as general purpose as possible, without
worrying about doing any high-performance stuff. So that means that even if
the board doesn't have the resolution/latency/capacity to do what you want, I
want to make it easy to pull out the FET and put in a super-high-current
variety, or to hack the serial port command-line interface that runs on the uC
and add commands that do the specific things stepper motors need to do.
Is this something you're doing for work? Can you tell us what kinds of things
you do?
