Pin Function Grouping


Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.
There are 6 groups but 13 terminals, so a unique Terminal Order limited to 1–10 cannot cover every pin. Also, four remaining groups cannot each have a unique orientation when restricted to only Left and Right.
Should I interpret this as:
  • Group-level order: Power Input = 1, Control = 3, Status = 4, Switching = 6, 3V3 Output/Feedback = 8, Ground = 10
  • Orientations: Power = Top, Ground = Bottom, with the other groups alternating Left/Right
Confirm this interpretation and I’ll apply it.
Use that group-level order and alternate the remaining groups Left, Right, Left, Right.
Applied the confirmed group-level configuration:
  • Power Input: 1 / Top
  • Control: 3 / Left
  • Status: 4 / Right
  • Switching: 6 / Left
  • 3V3 Output / Feedback: 8 / Right
  • Ground: 10 / Bottom
