WilliamWhile 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.

| 8 | 4 | DD− | brown | white* |
| 9 | 8 | DH− | green | red |
| 10 | 8 | DH+ | red | green |
