Technique for Using Pogo Pins for Solderless Programming & Testing PCBs with Castellations

Hackaday.io user Ankit Bhatnagar designed this pogo pins-based adapter for programming ESP8266-12E SMT modules without having to solder directly to the modules. It’s a clever trick that could be modified to other boards and designs that use castellated mounting holes:

Made this adapter to program and test esp8266-12e modules. Since these modules would end up in my final build, I was looking for a solution that would let me program them without any soldering. Using pogo pins allows for simple connection without any soldering involved

I’m curious about the ‘action’ myself; with secure solder joints I imagine the module slides in one way with ease, then locks into the other side. I also imagine it was a bit tricky, but that the pins were soldered into place with an actual module on the adapter holding them steady. And I look forward to seeing the final project these modules go into too!
