Hey folks,
Just a quick confirmation. Can I use an arduino uno and Ethernet shield with RFM? It looks like the RFM CSS goes to 8 instead of 10. I would like to make sure everything is up and running my spare unos before I purchase minis.
Thank you for your great work.

Technically yes at least for a short time. Regular UNO's are 5v but the RFM needs 3.3v power AND signal. It will however last about 9 days at 5v... You can also mod your UNO by replacing the regulator, removing a resistor and adding a diode. Really pretty easy, I've done it. Adafruit has a tutorial I believe. If you buy a Buono it can switch to 3.3v and has the same form factor as an UNO. Regards,

Thanks for the quick reply. I should have been more clear that I am using a Buono set to 3.3.
