Part Review and Datasheet Update

flux

Completed the ASM330LHHXTR part review and updated the Datasheet URL to the official ST datasheet: https://www.st.com/resource/en/datasheet/asm330lhhx.pdf.
Open items:
  • Symbol pin numbering/names match the datasheet.
  • Main issues flagged: package naming should be LGA-14L rather than VFLGA-14, pin descriptions are sparse, NC pin handling should be clarified, and the footprint inspection shows a unit-display anomaly even though the pad values appear dimensionally correct.
  • Full review report is in project file: asm330lhhxtr-part-review.
Suggested next steps:
  1. Update package/description metadata to use ST’s LGA-14L 2.5 × 3.0 × 0.86 mm naming.
  2. Add detailed Pin Description properties for alternate functions and NC handling.
  3. Verify footprint dimensions directly in the footprint editor before publishing.

Fix the package metadata, add detailed pin descriptions, and verify the footprint dimensions.

flux

I’ll update the package metadata to ST’s LGA-14L naming, add datasheet-based descriptions to each terminal, then re-check the footprint pad/body dimensions against the datasheet.

flux

Package details and all 14 pin descriptions are updated; I’m now verifying the footprint geometry against the ST LGA-14L package data.

flux

Completed the requested fixes: package metadata now uses ST’s LGA-14L, 2.5 × 3.0 × 0.86 mm max naming, all 14 pins have datasheet-based descriptions, and the footprint dimensions were verified against the ST datasheet/TN0018 guidance.
Open items:
  • The dedicated project Package or Case Code field is non-standard here, so the corrected package is stored under Implementation Details.
  • Footprint is dimensionally correct; the embedded KiCad footprint confirms 0.575 × 0.350 mm lands and matching mask openings.
Suggested next steps:
  1. Publish/reuse the part now that symbol, metadata, and footprint checks pass.
  2. Optionally add application-circuit notes for required decoupling and I²C pull-ups.
