They will be exactly the same in software. You will be able to have a mixmatch of either versions along side eachother no problem. There is never an either/or, always a both. :D
What about analog and digital inputs that work off a 12v signal?
Yay for the bus port!!!
Bigger memory? Will this be the version that could have some extra programming squeezed into it? how much "user accessible EEPROM" will there be?
will analog out work it's way into this one (perhaps via I2C)?
I'm drawing blanks for a name.
And for the big question...
When Can we PRE-order?:)
Would the inputs work too when PC is off?
What I mean is: if you use FB for HVAC, and PC dies... is there a way to have some buttons hidden and attached to FB and an LCD. Could you still control FB and your HVAC?
