Question for you 3.3v proc users
September 11, 2009
Heya fellow lmr folks.
So I've been using procs that are 5v powered and sensors that align with that voltage as well so I have a nice collection of various devices that I can use in this power range. Since I'll be working on a project based on the xmos chip I noticed that it's a 3.3v chip...and my problem currently is I'm not familiar with using 5v devices with the 3v procs. I've searched google and found some info, but wondered if anyone else had resources for doing this. I want to be sure I cover my bases and don't fry the board on the first try. releasing magic smoke! DOES NOT WANT!!!
Basically what I'm looking for are words of wisdom from the folks who have delved into this area and what they've found works well, and what doesn't work well.
Any insight/info is welcome!
