Brian,
There are to many variables to do what you ask. It's hard enough to get
several motors in a relatively equal group done right much less a blanket
design. As for ExpressPCB, I don't use them, you have to use their software to
design the PCB and that is very limiting. I use a software that goes from
circuit layout to simulation to PCB. It generates BOMs (Bill of Materials) for
my editors and articles, Gerbers that I can send to any board house and even
simulate microcontrollers. as you might expect it's not the cheapest product but
it works very well and saves me hours if not days and weeks of time.
Best,
Rob |
