Hello, I've got a small project using XBees. I've already gotten the meat of the project to work, the software is done, everything works great. So now my task is to take the arduino (which is more or less simply being used as a nice 3.3V power supply) out of the loop and just use a wall wart to directly power the XBee.
What I have is a 9VDC/650mA wall wart, I have the barrel jack, a breadboard, and a 3.3V regulator (LD1117). My admittedly simplistic mind figured I could just plug everything in as per the datasheets and be good to go. Well a burned finger and dead XBee module (as well as some burned pride ) later, I'm left figuring out what I need to do to supply the danged XBee with 3.3V from the wall (no batteries in this project). I have some 5V regulators as well (NCP7805) so if I need to use some combo of them, or throw in some caps/resisters, help me to understand this seemingly basic circuit!
