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!

ESP8266 SMT Module – ESP-12E: Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. We do sell these on a breakout, but maybe you wanna just put this in your own project PCB. Read more.
