Hi Ted,
?
One thing to remember is the difference in display current requirements.? The V6 is a touch screen with graphics capability, while the V5 is a 16x2 text display.?
?
Also, note that the v6 Raduino already has a heatsink on it.
?
I would be careful with the 10-ohm resistor.? If you use that on a v6, you may drop below the minimum input voltage for the 7805 (approx 7 volts).? This will depend on the supplied voltage.? Assume a 10-ohm resistor will drop the voltage by 10 volts at peak load.? A better value for 14 volts would be a 6 or 7-ohm resistor.? The resistor should have a 10-watt rating.? A more reasonable choice would be a 5-watt 5-ohm resistor or five 1-amp diodes.
