Don't Connect/Route Power Pin

e14 Contributor

Hi everyone!

I'm making an Arduino Due Shield, and at the Main Board there are Output Power Pins (+5V, +3V3), which I use in my Shield.

The problem is that those pins are being connect one to each other (Output to Output) and not only to what is being used in my Shield (as Input).

Those Output Power Pins are in a simple Header.

Is there someway to tell the program to don't connect them?

 

Thanks!

    Thanks for the replies and tips!

     

    My problem is with Auto Router. There are some headers which provide +5V and +3V3 to my shield, but those +5V are begin connected to each other, even when they are an Output, what wouldn't be necessary.

    For example: There are the +5V in ICSP header and +5V in Power Header, they don't need to be connected to each other, as they are the same Output. This cause a wast in Auto Router as it routes the unecessary wire.

     

    Is there a way to make it don't waste Auto-Routing those wires?

    Really? You have two pins that you have explicitly placed ON THE SAME

    NET in the schematic, thus telling Eagle that they need to be connected,

    and you're complaining that it tries to connect them?

     

    If they shouldn't be connected then they can't be the same signal and

    you need to not have them connected on the schematic.

     

    If they are the same signal and should be connected then you WANT the

    autorouter to connect them.

     

    If the power header and ICSP header both have pins for the 5V supply,

    and it's the same 5V supply, then both pins need to be connected to the

    5V supply and thus to each other for the board to be correct.

     

    If you don't like the particular route that the autorouter lays out then

    do that routing by hand. Just don't blame the tool for doing what you

    tell it to.
