Pin Grouping Functions


I’ll inspect the current symbol pin list, organize pins into functional groups such as power, ground, reset/debug, clocks, and interfaces, then verify the updated symbol.
Grouped all 49 pins by function:
  • Power: 3V3, Ground, Analog Power, Backup Power, Core Regulator
  • Clock: HSE and LSE
  • Control: Reset and Boot
  • GPIO: Ports A, B, and C
Pin orientations and ordering were also organized while preserving all pin numbers, names, types, and symbol positions.
VSS and EP are ground
Correct. VSS_1, VSS_2, VSS_3, and EP are all assigned to the Power → Ground group. VSSA remains under Analog Power as analog ground.
Make the functional group more general
Should I simplify the Section categories to:
  • Power — VDD, VSS, VDDA, VSSA, VBAT, VCAP, EP
  • GPIO — all PA/PB/PC pins
  • System — clocks, reset, and BOOT0
The detailed Pin Groups (3V3, Ground, GPIOA, HSE, etc.) would remain underneath.
Simplify functional sections
Keep only power detail
Group all GPIO pins
