Typically, one uses a lab power for such purposes. But at least on the desk where I do the programming I don&rsquo;t have one. Since these systems typically consume little current it would be handy to be able to power them from USB. Most of my devices have on-board regulators so the voltage is rather uncritical. For 3.3 volt devices, the 5V from USB is just right. But others have a 5V regulator so they need a higher supply voltage. And even others might even need 12 volts.</p>
