Moteino Performance, Breakout board for RFM69W?

My compliments!  I paired a Moteino 915MHz on one end with a RFMW69 on a homemade breakout board that I added to an existing Arduino Uno config on the other.  I was able to get clean communications using your Gateway and Node demos from the basement of my house to the 2nd floor of a detached garage that was 100 feet away.  I then tried from inside the house to outdoors down the block and was able to effectively communicate through the exterior wall and external obstacles up to roughly 450 feet.

The only issue I had was when I relied on USB power on the Arduino Uno side.  There was already some current load (a few LEDs) and going into transmit apparently added enough additional load to intermittently drop the voltage to the point that the Arduino reset.  This had me going for awhile and thought a heads up might be helpful to some.

I plan on buying more of the Moteinos, but I now have an issue.  I mentor students who have already purchased a number of Unos and need to find an easier way to add RFM69Ws to them.  The custom breakouts are a pain!

Do you have or know of a breakout board that includes the 7 required .1" pitch pins (GND, SCK, MISO, MOSI, CS on one side of the RFM69W, and 3.3V and D2 int on the other side)?

Thanks!

You mean something to plug in directly to the UNO?
That would probably be harder because the power is on one side and the data pins are on the other. Perhaps an Arduino classic shield would work better but that would be a bit of a waste of PCB for such a small transceiver.
I don't have a dedicated PCB unfortunately for this purpose.

I suppose I could offer bare Moteino PCBs which then you could solder the radios onto, and then all the RFM69 pins would be available on the 2 side headers. Then you could solder male or female headers and connect them to the UNO that way. Except the antenna would have to be soldered directly on the Moteino PCB, which is a good idea anyway. Would that work for you?

There is a seller on E-Bay called "Anarduino" in Texas who sells a breakout board for the RFM69 Modules.
I think that may be what you are looking for. I have a couple of them that I recently purchased that I am hoping
to get going with the Arduino UNO. Do a search for "RFM69W Breakout Board" on E-Bay and it will take you
to the item.

Hi Vince and Felix,

Thanks much for taking the time for your prompt replies!  Felix, I should have mentioned that the students use small solderless breadboards for their projects, so the breakout board would not need to plug directly into the Arduino.

Vince, thanks for your suggestion.  I picked up on that vendor as well in my Google search.  The issue with that solution is that it does not pick up the 3.3V and D2 int pins on the opposite side of the RFM69.  However, it is certainly an improvement on the handmade solution I used in my proto, as it reduces the number of required jumpers to two.  From your note I'm assuming you haven't seen any problems with them. 

I just wanted to be sure I hadn't overlooked any alternative "perfect" solutions that might be out there. 

Thanks again!
