 		 #189421 - That's very true, and it's convenient, too ...
Responding to: ???'s previous message
... but the moment you have to power external hardware in order to perform useful work ... well ... you need power, and the DevBoard won't always be enough.

Suppose he wants to drive a couple of steppers ...

The point of my previous post was that, though one can build a PSU, it's best to have a commercial, benchtop power supply, usually a triple-output with one pair of outputs capable of tracking and the other mainly for logic, hence switchable or adjustable from just below 2 volts up to, say, 5 or 6 volts, with, say, 3 or more amperes of output current, and with current limints, and the selectably tracking or not other two with complementary outputs between 30 and 0 volts, normally at somewhat lower current. I've got one that's 30+ years old, and has served me well. Since I'm into testing, having it GPIB-interfaced as well as front-panel operable is very useful.

      helpful.            01/01/70 00:00      
   You do realise that 8-bit != 8051 and 32-bit != ARM?            01/01/70 00:00      
      yes I understand.            01/01/70 00:00
