Using boards like the Uno and a MiniPro(5v), I've successfully done some analog sensor reading. Most of my sensors require an accurate 5v excitation voltage, so I just use Vcc on the 5v arduino boards. But now I'm trying to use these same sensor but on some 3.3v boards (Fio, JeeNode). I tried using…

precise 5v for sensors with 3.3v arduino?

Maybe I just need to use a different boost converter. It would be great if that's all I need since it's a very simple solution. Any recommendations on a boost converter?
