Hi Tom,
I kinda agree with you, you know what they say, if it's not broken, don't fix it! Keep it simple.
Extra analog inputs are always good if there are still pins available on the processor, why not.
How would you go about an I2C Pitot Tube?
BTW, I love this project, you have done wonders since it started. Very nice platform, simple interface.
All that is missing is the ground station. I wish I knew how to code stuff like that so I could contribute.
Regards,
Olivier
