ESP-12 breadboard adapter

thingiverse

This is an adapter designed for ESP-12 modules, allowing them to be programmed or used directly on breadboards. When working with multiple modules, a convenient mounting solution can simplify the process before final soldering or integration takes place. The 3D prints enable spring pins to match the 2mm spacing used on these modules, securing through the holes and allowing for a snug fit. A retaining bar may be employed for added security, but it's not necessary for quick programming sessions. To maintain accessibility on breadboards, the adapter's width is minimized. The required components include 3D printed parts, 16 spring pogo pins (1mm diameter, 16mm long), two 8-way single-in-line jumper posts, and two M3 countersunk screws with nuts. To prepare each pin, solder a fine wire about 3.5mm from its base, using a minimal amount of solder to prevent shorts. The wire should be 0.2mm thick and sourced from a multistrand cable. Next, insert the 8-way headers into the base slot with their short side facing up into the pin cavity. A small amount of glue can secure them in place for added stability. Insert each pogo pin individually into the blind holes in the base, soldering its tail onto the header pin. Position the pin alignment part over the pins and push down gently to secure them in place. Tweezers may be used to align each pin into its corresponding hole. Finally, insert the countersunk screws through both parts and secure them with nuts.
