The scale is slightly wrong. Note the bottom left wire is not straight. The pins should be exactly on a 0.1in boundary and they are not. You likely need to rescale the image slightly to correct this. The bottom two right connectors are not correctly defined and thus don’t connect. The ratsnest line comes from this connection in schematic (which is almost correct other than the terminalIds)
there should be a terminalId=“connector3terminal” added to the schematic connector entry above. The pcb svg is the wrong scale. The pins on the board should be in the same place as the header beside it as one is supposed to connect to the other.
In pcb the pads need to look like this to cause Fritzing to drill a 0.038in hole in pcb. As well the silkscreen stuff should be deleted as it typically isn’t used (it will however work as is unlike the pads!)
If the original poster made the changes I suggested above they didn’t post a new version of the part. That said, your new version still has a number of problems, mostly cosmetic but the pcb hole size is only 0.036in and they need to be 0.038in to fit 0.1 header pins so your new board probably won’t work either. The breadboard svg is still missing its layerId and thus won’t export as an image.
all the stuff and pin numbers should be deleted, the outside edge of the board should be 10 thou wide and be the outline of the complete part and as noted the holes in the pads should be 0.038in like this (taken from the gerber output drill.txt file)
; NON-PLATED HOLES START AT T1
; THROUGH (PLATED) HOLES START AT T100
the line T100C0.036000 indicates that the holes defined as T100 are plated through, and 0.036in in diameter. The T101C0.038000 indicates that the T101 holes are plated through and 0.038in diameter (and are the 0.1in headers I added to the sketch!) Here is a corrected part that meets the graphics standards and is ready to be added to core parts.
Thanks Peter and sorry about the hole size being wrong. I actually just copied and pasted the holes from the svg of the arduino nano part. Anyway great news that the community now has the esp32 devkit part.
