[MinnowBoard] 1.6V output on gpio pin

[Trevor Woerner]

Yes! This is awesome stuff and I'll gladly take all the help anyone 
wants to provide. Thank you :-)

At this level (driving LEDs and stuff) my past experience is with PICs 
and ATMELs (which are now the same, I guess), and with them it was quite 
easy to hook up an LED directly to a pin (with a resistor) and start 
toggling. But it makes sense (now) that a modern, highly dense part 
(like what's in the minnow) would behave very differently.

Is the switch you drew considered a buffer? If someone said I needed to 
add a buffer to by design I would imagine something involving a 
flip-flop (but, as you can see, I'm still getting familiar with this stuff).
