STM32H503 Pin Grouping


I’ll consolidate the symbol into 10 ordered functional groups, assign Power as order 1/Top and Ground as order 10/Bottom, then alternate the other groups across Left and Right and verify all 48 pins remain intact.

Received notification from "STM32H503 Symbol Grouping" that it finished — picking the work back up.
The 10-group update is complete. I’m checking the final order/orientation assignments and terminal count before closing.
Completed and verified all 48 terminals:
  1. Power — Top
  2. Clock HSE — Left
  3. Clock LSE — Right
  4. System — Left
  5. GPIOA Low — Right
  6. GPIOA High — Left
  7. GPIOB Low — Right
  8. GPIOB High — Left
  9. GPIOC — Right
  10. Ground — Bottom
No pins were added, removed, duplicated, or split into sub-symbols.
