Exact width between header rows

Hi.

I haven't been able to find any exact information about the width between the rows of the mbed, only that it's a "DIP form factor", whatever that means.

The handbook tells the height and width of the whole unit (54mmx26mm) but not the width between the 0.1 inch header pin rows. I suppose this is in inches since it fits breadboards.

Could anyone provide me with the width between the headers, or if it exists an exact mechanical layout of the mbed?

Thanks.

They're 8 holes apart (0.8"?). On a typical breadboard with 10 columns A-J, plug into columns B and I, leaving A and J visible.

Thanks FRiC. It sounds logical, sorry for the dumb question but I don't have the mbed here.

Does anyone have a component layout and outline for the mbed in for example the dxf-format?

It would simplify my job of making a 3d represenation of the mbed in Altium.

The spacing between the two rows is 0.9" as discussed in this thread:
