I have the same question about boards for S5, I wonder if I could insert a S5 board into a S3 control board.
Have anyone tried that?
nope
s-3 for s-3
s-5 for s-5
s-7 for s-7
s-9 for s-9
r-4 for r-4
if you flash the s-9 controller with r-4 firmware maybe it works
I seem to recall reading that. and I have not seen it demoed.
Interested how possible flash control board s-7 to s-9?
I know that this different firmware.. Do you have experience update s-7 to s-9?
