These two parts should do what you want. One (the tht part) is for use with 0.1 headers. It has all the pads accessible in breadboard and schematic but doesn’t emit the pads in pcb (as they aren’t through hole, only SMD.) To solder the part to a a board use the SMD version of the part.
I truly appreciate the time and effort you put into creating the Fritzing part for the DFR0975 board. It works perfectly on my end, and having a proper custom part makes a big difference to my workflow.
Thank you again for your generous help—this saved me a lot of time and trouble. Really grateful for your support!
