Thanks to both replies. The idea is to create a “sockets board” so basically all these 5 pins sockets will be directly soldered to this board, and then the board will have a header that will be wired to the main board (MKRFOX1200), so I don’t have a million wires floating around.
So yes, direct solder to the PCB is the intent. No wires from socket to PCB.
I don’t know where to find the maker for this sockets, like you said ebay doesn’t provide much information and I can’t find more detail on them. I wish I found these on RS or Digikey as they always provide the full datasheet with all dimensions.
I will check tutorials on them and see if I can deal with manual measurements…
