A few more electronics queations before I order. I have done some searching and some reading but still have questions about supplying power to the C32 and ESS. I like the idea of optoisolated inputs and outputs and am trying to get a head count on 5v supplies. It looks to me that (1) 5v 3a will cover the main power if the C32 and ESS. Then I would need (1) 5v for inputs (limit switches) and (1) 5v for outputs (drivers) for a total of (3) 5v supplies. Is this correct and or necessary? With my lack of skill level on electronics I would rather buy a few extra supplies rather re-buying everything when I short something out.
Thanks
