Pin Function Grouping


Grouped all 24 pins by function: Power, Ground, RF, USB, Digital Interfaces, Control, Timing/Interrupt, Status, and Reserved. Pin ordering was added within each group, while preserving pin numbers and existing symbol positions.
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 define ten ordered functional groups, place Power first and Ground last, alternate the other groups across the left and right sides, then verify every terminal.
Assigned the ten functional orders and orientations:
  • 1 Power — Top
  • 2 RF — Right
  • 3 USB — Left
  • 4 I²C/SPI — Right
  • 5 UART/SPI — Left
  • 6 Control — Right
  • 7 Timing/Interrupt — Left
  • 8 Status — Right
  • 9 Reserved — Left
  • 10 Ground — Bottom
All 24 terminals were verified.
