Pin Grouping By Function


Move GND_1 through GND_30 into a separate Ground section, retaining their Ground pin group.
Moved GND_1–GND_30 into the separate Ground section. Their Ground pin group remains unchanged.
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.
I’ll use Terminal Order as the section rank: Power 1, Control 2, GPIO 3, USB 4, UART 5, Not Connected 6, and Ground 10. Power/Ground will be Top/Bottom, with the other sections alternating Left and Right; unique orientation per section is impossible because only four orientation values exist.
Applied the section ordering and orientations:
  1. Power — Top
  2. Control — Left
  3. GPIO — Right
  4. USB — Left
  5. UART — Right
  6. Not Connected — Left
  7. Ground — Bottom
