Hi, I ordered this some time ago and am finally getting to use this in a project. I have a pair communicating very nicely through several walls. Both are mounted on Arduino Uno's. However, I want ethernet connectivity. So I bought an ArduinoEthernet board that has the ethernet integrated (not as a separate shield). However, the RFM22 and ArduinoEthernet combination fails to initialize. My guess is that they are both sharing some I/O pins. Is there any way to figure out what the conflict is? Thanks in advance,

Never mind, it looks like there are really only 2 choices, and that either one will work.
Sorry, one more question: I'm new to this PIC stuff. Will any 18-pin chip work, or do I need to use a specific chip?
The schematic calls for a 12v supply. The related and recommended products below show a 9v supply. Is it know for certain that this supply is compatible with this board?
