Pin Grouping by Function

A

adrian95

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 assign a consistent group-level order from Power (1) through Ground (10), alternate the remaining groups between left and right, and verify all 25 pins.

flux

Assigned and verified the group-level ordering and orientation:
  • 1 Power: Top
  • 2 VDD / 3V3: Right
  • 3 Reset: Left
  • 4 Oscillator: Right
  • 5 GPIOA: Left
  • 6 Analog / GPIO: Right
  • 7 Reference: Left
  • 8 SWD: Right
  • 10 Ground: Bottom

Make every Section value exactly match its Pin Group, then preserve this order and orientation.

flux

Updated every Section to exactly match its Pin Group. Existing terminal order and orientation were preserved.
