Pin Function Grouping


I’ll inspect the connector’s terminals, group them by function, and keep each pin’s Section aligned with its Pin Group.
Grouped all 13 pins by function:
  • Power: VCC
  • SPI: CS, DI, SCK, DO
  • Card Detect: CD, CD2
  • Ground: GND pins and SHIELD
  • Other: NC, RSV
Each pin’s Section matches its Pin Group, with consistent orientation and ordering.
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.
Updated the terminal groups:
  • Power: Order 1, Top
  • SPI: Order 3, Left
  • Card Detect: Order 5, Right
  • Other: Order 7, Left
  • Ground: Order 10, Bottom
The remaining groups alternate between Left and Right since three groups cannot each have a unique orientation using only two allowed sides.
