I was doing some research on basic stamp stuff on the Board of Education from parallax and thought of this question: what is the point of X1?

I guess it's for plugging in a daughter board, or a cable to an expansion board. What does it say when you RTFM?

 

I, like papabravo, would guess that it is an expansion port that is provided for an expansion board.

Do you have to have it?

It look like X1 is a combintion of X2 and X3. Purpose is not stated.
