Is X2 or the DC jack going to "run into" the USB connector or DC jack on the Arduino below?
not going to cause problems, but its not very neat
In the PCB, those vias that are placed around the ground plane are not actually connected to anything, I'm guessing they're meant to be connecting the top and bottom planes together?
Did you NAME your Polygons and the Vias GND?
QuoteIs X2 or the DC jack going to "run into" the USB connector or DC jack on the Arduino below?nothing of both is running into the arduino. Only the header connectors. I thought its better to completly leave the arduino out of the 12V opposing to plug the jack into arduino and grab the 12V from vin, isnt that correct?
Im still not certain with that dc connector, even in the schematic it looks odd.
No I mean physically run into.
the meaning of the dc jack schematics symbol is not obvious to me.
X3 pin 4 has a "less than 90 degrees angle"
Name your vias GND so it connects both top and bottom copper layers
Why not use pads instead of vias to connect your wires?
I think your pads are too close to the edge. DRC didn't like it.
I use the vias for their holes to put headers in them so that i can attach my shield on top of arduino.
Why doesnt drc like my library part consisting of vias, but likes plain vias at the same position with the same size? I could just place a Via same size same distance next to my existing header-vias and it would give me no error.
