I’m working on a project where I would like to replicate the mounting like on this HopeRF module. Kind of a general design question but as I’m using KiCad I thought I would ask here. I don’t even know what you call this. 
The idea is that the user can solder standard 2.54mm pitch pins to allow for through-hole breadboard applications OR design a PCB with SMD footprints and solder it down using the half round plated edge holes. 
I tried just adding a second row of holes to the edge, with the idea that when the board is panelized I can specify a v grove between them? 

So my real question is what’s the best way to design / specify this kind of thing for manufacture?

This is my attempt. It renders badly the way I’m doing it as well.
