Does anyone know what the pin spacing is between the two rows of 8 pins? Images that I've seen say that the spacing is 16mm. The board that the ESP-12 is mounted on has a row of half holes and full holes in each side. In looking at these imaging it is not clear if the 16mm spacing is from the outside half holes or the inside full holes. Does anyone know?

I've just received my ESP-12 this afternoon. It's look like the 16mm is not even half holes measurement, but the whole board outline. (but my ruler isn't precise)

The center-to-center spacing of the full holes is 14.3mm. I've already designed a few PCBs for the ESP-07 and ESP-12 modules and this value is correct.

Here's a breadboard adapter with 14.3mm spacing...
