Have a Uno board right now that I am playing with. I have a nice BK Precision power supply on my bench that outputs a very stable and clean +5VDC to my breadboard setup, to which my Uno is velcro’ed to. I would much prefer to power my Uno from the +5VDC supply instead of separate wall-wart or 9V battery for simplicity of wiring and convenience. The other two output from my power supply are being used to give +15VDC and -15VDC to some op-amps used on the same project. From what I have gleaned from the web, this is very possible. First, am I correct in this regards. Secondly, do I just plunge right into the +5vDC bus on the board, or somewhere else specific. Lastly, what pit-falls do I need to be aware of if I go down this route. One thing that pops to mind is to make sure I never have the USB hooked up and my +5VCD power supply attached at the same time. Anything else?
Yes, I know that the Uno board might not be my best option. I'm still working through the hardware and software requirements for my project, and the Uno offers me all options until I figure out exactly what I don't need. Thanks!
