I prefer the Esp8266; Esp11's and Esp12's for my projects, but interfacing to tightly spaced pins can be challenging. In past (see previous blogs) I have used several methods to make the connection to the edge "Castellated" pin-outs.
What is needed is an adaptor for the Esp11's 1.27mm (50mil) pin spacing and the standard 100mil protoboard spacing.
The following is my solution for the Esp11, a small board produced by OSHPark.com. I have made this board available for your use via a shared project, at:
Let me know if you find these useful, Thanks.
The Adaptors are so inexpensive, 3 for $1.00, that I suggest ordering them in groups of 12 or 24, the larger count makes the postage and PayPal charges more tolerable for OshPark.

|Ready for Solder|
Note: the hole conductor is slightly "curled" (distorted) by the cutting process, but that is not a problem as the curl will be encased in solder when used.
|Pin Alignment with Esp8266-Esp11|
|The Pin Pitch is 1.27mm (50mils)|
|Solder Is Used as Jumpers|
|Solder Jumpers were Installed in Groups|
|Pin Headers (100mil) are Added|
|Ready for Use|
Some of my Esp projects are available online, see previous posts.
