Step 4 — Cross-check: schematic symbol and footprint vs datasheet Summary: The mapping of pin numbers 1–55 appears consistent with the datasheet, the footprint geometry matches the recommended land pattern dimensions (pitch 1.00 mm, pad size 0.70 × 1.15 mm), and mechanical outline is consistent with 15.0 mm × 10.0 mm for the B3x2 family. A few naming inconsistencies and a variant-specific antenna nuance should be addressed.
Symbol pin naming/numbering cross-check
Footprint cross-check (geometry and pins)
  • Footprint source: NINAB30200B00.kicad_mod
  • Numbered pads present: 1–55, central ground pads G1–G12 present (total 67 pads)
  • Pad sizes in footprint:
    • Perimeter pads: 0.70 mm × 1.15 mm (matches datasheet recommended values)
    • Central ground array pads: 0.70 mm × 0.70 mm (consistent with inner pad guidance)
  • Pin pitch: 1.00 mm for outer rows (matches datasheet)
  • Module outline in F.Fab: 15.0 mm × 10.0 mm (matches datasheet B3x2 dimensions)
  • Orientation: Pin-1 marker is present on the top-left; perimeter pad numbering and side ordering look consistent with datasheet illustrations.
  • No mismatches found that would cause assembly issues when following this footprint. Presence of inner G pads (G1–G12) is consistent with exposed ground pad arrays used for thermal/RF grounding. Keep them tied to ground in board usage.
Potential risks / corrections to prevent issues
  • Symbol naming cleanup: rename the three pins noted above to match datasheet (avoid underscores that are not in the official names).
  • Antenna pin handling for B302:
    • ANT should not be used or routed on NINA‑B302 (B3x2 internal antenna). Mark as NC or hide. Leaving it as an I/O could prompt erroneous RF routing.
  • Inner ground pads:
    • The G1–G12 pad naming is a library convention (datasheet labels these collectively as exposed ground pads, not individual “Gx” numbers). This is fine, but be sure they are declared as Ground/Power pads to encourage correct net assignment during schematic use.
If you want, I can apply the symbol pin renames and update the ANT pin type/annotation for this part.
