Pin Grouping by Function


Grouped and ordered all 35 pins into:
  • Power
  • Ground
  • Analog Support
  • Analog Inputs
  • LED Drivers
  • SPI
  • GPIO
Pin names, ball numbers, positions, and footprint mappings were preserved.
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 currently 7 groups, but only four orientation values: Top, Bottom, Left, Right. Therefore, giving every group a unique orientation is impossible, especially when the five middle groups must use only Left or Right.
Should I alternate the middle groups between Left and Right, while assigning group-level orders 1, 2, 3, 4, 5, 6, 10?
Alternate the middle groups between Left and Right, using orders 1 through 6 and 10.
Assigned group order and orientation:
  1. Power — Top
  2. Analog Support — Left
  3. Analog Inputs — Right
  4. LED Drivers — Left
  5. SPI — Right
  6. GPIO — Left
  7. Ground — Bottom
