The nRF24L01 comes with dupont wire friendly pins. The RFM69 do not. You have to do some soldering.
I've found that using 22 gauge wire and soldering them onto the RFM69 is the easiest way. I've tried male pins with the 2.0mm pitch and matching female dupont cables, but the connections are shaky. Best to just solder wires directly.
For my projects, I've decided to go with these RFM69 modules. No interference from wifi. Better wall penetration, goes six times farther. The high gain (20dB) version of the RFM69 is cheaper than the high gain version of the nRF24L01. I don't know much about antenna design, but a simple 22 gauge wire about five inches long does what I need.
I haven't gotten around to implementing what I want to do with them. Need to figure out how to pass along a user defined struct.
