Wiring a RFM69 radio

[user2684]

Hi, I want to recommend to new users (like myself) to buy some additional items when going for a RFM69 radio. I've discovered in the hard way that this radio has a 2.00mm pin spacing and not 2.54mm. This means that unless you want to solder each pin individually to your arduino, you need some additional piece to wire the radio. First of all, you need to solder 2.00mm pin headers like this one:

Then you have a couple of alternatives. The first one is to use 2.54mm to 2.0mm Female cables like the following:

Alternatively, this 1.27MM 2.0MM 2.54MM 8pin adapter board is very handy if you want to use traditional cables:

I don't know if makes sense to have these or something similar into the MySensors store as well.

Thanks!

Nice recommendations @user2684, thanks! I have been soldering wires which works quite well, but I'll order the headers and converters to use for future projects.

I use these and they plug straight into my Gert Saunders boards with no wires

Only for rfm69hw or rfm69w not the compact version.
They work a treat
