is attached pictures of the PCB pad layout used on the K4 and KT2

On page two is a drawing of the recommended pad layout for the connector.
Step one in making a matching Pyralux overlay is to verify that Amazon/Lab126 is using the recommended pad layout.
If not, then determining what dimensions they are using.
