This I is not necessary, the usb connector does not limit the size of a shield The only limitation is that you probably cannot place components at the position of the usb connector on the pcb of your shield ( if you really need to make such a big shield). > > Counting this, and my limited experience, you must admit, I did a good > job :-P Yes, but only if it is working as it should A small tip, try only to draw traces horizontal, vertical or in 45 degree. A pcb must also be a kind of an art. You did not build this pcb yet did you? Because I think you will get problems with the components placed under the microcontroller even if you will use a ic socket. > > I can't wait to finish the first board (18F2550) to play with it.

They say it is not always the size that counts :-) Greetz Richard --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jallib" group.
