RFM69W Breakout Board

I wanted to experiment with the RFM69W radio on my existing Arduinos so I created a breakout board. The board has the same edge pinout as the RFM12B Board from JeeLabs so you can swap between them.
Details are here:
https://github.com/uChip/RFM69W_BOB
You can order the board from Osh Park here:
http://oshpark.com/shared_projects/bJRprI06
$6.75 for three boards (PCBs only).
Note that the board is NOT compatible with the RFM12B or the RFM69CW. Use the JeeLabs board for those.
Have fun.

Excellent! I ordered a few RFM69HW transceivers awhile ago and was going to hack up a solution that would allow me to plug them into a breadboard, decided to order your breakout boards instead.

Cool. According to the mechanical drawings that should work fine, but I haven't tested with the 'HW. Let us know how it goes.

uChip,
Nice idea on the Breakout Board, especially the level shifting resistor option. Do you have a parts list available for use with the Board? I just ordered three.
Thanks,
Vince

Note that all parts are "or equivalent". These are the parts I tested with, but you can probably substitute parts with no impact on function. For instance, any 0805 package 10k resistor would be fine.
Do check the repo document as not all parts are needed in all applications.
I will also add this info to the github repo.

Hi Why use a voltage divider vs a level shifting chip? Pro's/Cons?

Resistors will work just fine, cheapest option.
You can also use FETs or dedicated chips for level shifting, these are more complex/expensive solutions. For hobby stuff resistors are fine, if you are the military you might want shifting chips
