While working on a new pin specification for the Retro Modules project & a new project related to a Starlink PoE Injector (coming soon!), I realized I needed to define a 2.54mm header specification for this project.

This project isn't re-inventing the wheel -- just adding one.

The color code for ethernet cables is based on the 25 Pair Color Code. The spec below is as well.

Specification

Contact Pair Role Primary Wire Color Secondary Wire Color
1 2 DA+ white orange
2 2 DA− orange white*
3 3 DB+ white green
4 1 DC+ blue white*
5 1 DC− white blue
6 3 DB− green white*
7 4 DD+ white brown
8 4 DD− brown white*
9 8 DH− green red
10 8 DH+ red green
11 7 DF− orange red
12 5 DG− white slate
13 5 DG+ slate white
14 7 DF+ red orange
15 6 DE− blue red
16 6 DE+ red blue

* Optional Secondary Wire Color
