Hi,
While testing several transceiver types and frequencies, I was interested to use a kind of RFM shield, on top of a bare Moteino.
Having find a 2mm to 2.5mm adapter board on aliexpress, I have made some shields (each transceiver type requires it own shield).
Of course a nice PCB design should be better, but overkill for the small amount of configuration.
For those who are interested, details may be found under:

Note, not all of them have been tested, so if for any error, please leave a note.
