Thank very much Rob, now it's clear! On the expancion board, on Port 18-19-20 (where I can attach the float switch) it is normal that between GND and +5V I don't have 5V? I'm trying to understand how it works because I need to connect a "float" which is an open collector circuit...
thank you again
Simone
