Ok, so a little while ago I purchased two arduino nano's with the CH340 USB to serial converters. I have installed the drivers several times(windows 10). I am able to use the on board LEDs but not the gpio pins. On one of the boards I am able to get power from the 3.3v pins while on the other I am not able to.

That's disappointing - I've yet to see a nano clone that didn't do the 3.3v power right. Wonder what they screwed up?
