Pin Grouping Audit

flux

Audit and pin grouping are complete. The official datasheet URL and package were corrected, and a critical pin mapping error on pins 22–24 was fixed: 22=VDD_1, 23=VCAP, 24=VSS_1.
  • All 48 pins are uniquely assigned: Power 6, Ground 4, GPIO/Analog 27, Oscillator/Clock 4, Reset 1, Boot/Debug 6.
  • Every pin now has a description, electrical type, Pin Group, and matching Section; no pins are duplicated.
  • Footprint matches LQFP-48, 7 × 7 mm, 0.5 mm pitch, with pads 1–48 mapped one-to-one.
  • Remaining gap: no explicit part-level Description property was found, although the project description contains the device summary.

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.

I’ll assign one group-level order per section: Power first and Ground last, with the four remaining groups given distinct intermediate orders and distributed across Left and Right orientations.

Updated all 48 terminals:
  • Power: Order 1, Top
  • Oscillator/Clock: Order 2, Left
  • Reset: Order 3, Right
  • GPIO/Analog: Order 4, Left
  • Boot/Debug: Order 5, Right
  • Ground: Order 10, Bottom
All sections still match their pin groups, and pin numbers, descriptions, types, and footprint mappings were preserved.
