Although I have be experimenting with the Esp8266 Esp-11 (see previous post), my goal is to use the Esp-12 configuration for more complex applications. The Esp-11 configuration has only 8 pins, while the Esp-12 has 16 pins, and therefore more I/O options.
Breakout boards are available for each, but there are trade-offs; the Esp-12 Breakout Board is much wider than the Esp-12 itself. Even though the breakout Esp-12 Breakout Board is protoboard friendly (i.e., 0.1in spacing), it is so wide that there is little space to attach jumpers (I think only one hole row on each side is usable).
I decided to try the technique of bending header pins as necessary to match the 2mm spacing, I originally used this method on the Esp-11 (see previous post).
The pin spacing of the Exp-11 is smaller at 1.27mm, while the Esp-12 is 2.0mm. A good microscope is needed to solder headers directly onto either.

Now all that is needed is wiring-it-up and some software (Yeah, . . . famous last words).
