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:

Pin orientations and ordering were also organized while preserving all pin numbers, names, types, and symbol positions.

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.

Should I simplify the Section categories to:

The detailed Pin Groups (3V3, Ground, GPIOA, HSE, etc.) would remain underneath.
