Hello Dan,
??? Sorry for the delay , I have been? busy still trying to use various .ino files without sucess.
To answer your query; If you do a google search for "Si4432 module warning"? I think that
you will see the appropriate information. It is a forum message (though I don't know what forum) and shows three red PCBs (one works, one is poor and one is bad). Guess which ones I bought! There is also a blue PCB which is said to work.
??? Banggood do that one. So as I have got nowhere? trying to test the ones that I have I will order two from there in case I get back to this project someday.
