I built these for my own use, a PCB that will interface a Moteino, Moteino MEGA or HopeRF RFM69H(W) radio to a Raspberry PI2 (its should also work with a B+, but I do not have one for testing)
Board is about 2.1 x 2.75... At this point its still a prototype, not a production board.
I have a few (6) extra board (PCB only) at $8 each with shipping in USA. (contact me direct tom .. at .. lafleur .. us)
Full information with schematics and Gerber files located at:

Quite nice work, thanks for sharing it! ;)
Hello,
You should be able to avoid jumper P2 by putting resistors on the TX and RX lines:
