No the RFM12BP (and lower power RFM12) uses a completely different RF chip. Although there are probably arduino code for it somewhere on the intarwebs since it's been around for a while.


Ok, will be easier to maintain rfm22 and when everything is operational, use the rf2126 booster mentioned by msev (datasheet says it is compatible with 433MHz).

What would I have to modify in the circuit to use it for 433MHz? In regards to that example circuit for 2.4GHz?

Thanks, I must have had a "shortened" version of the datasheet... That looks great..hope these chips will still be available once I get to the stage of building a booster...Dfidalgo if you build it be sure to post some pics of it, a tell where you got the chip  :)

Today I received the Zitron PCB's, look much better in my hands than here in the pictures !   :D
Now just need to buy the RFM22.

Thanks Zitron ;)
