With 270 Ohm resistor can I use all the analog pins?
What would be good step-down converter for 3.3V output? The DC voltage available may vary a lot from 9V to 16V (around 12V) or from 18V to 30V (around 24V), so I need converter that accepts wide input voltage range and stable 3.3V output.
With external power can the GND pin sink the current without overheating?
