Hi,
I'm also looking for a blank Rapsberry Pi Hat unfortunately it looks like the problems still the same: there is no PCB shape in core library who match the RPi Hat dimension.
I know there is a SVG file posted by steelgoose in this thread but I have absolue no clue how to import this SVG file in order to create a PCB shape in Fritzing.
Any chance to see this PCB shape available in core library soon ?
Thanks you
