What are the dimensions of a single pin? Mainly looking for 3 measurements. The 2 metals parts and the black part.

1/8" between the metal pins and 3/16" on the blacks. If you have a breadboard the pins fit perfectly.

Is it 2.45mm from the picture photo or 2.54mm from the description?

Never paid attention. But, it will fit the pi zero W with some trimming.
