Thanks Majenko.
Is the bigger one the Arduino Mega with only 256 Kb? Or is something bigger out there?
Anyway 256 I think would be much better than the 32Kb on the Nano, so it would be a good alternative and give us much more options when coding.
Anyway, in an era where everything is on Gb I don't understand why we are counting with Kb 
Thanks again Majenko
