Part Review and Datasheet Update

flux

I’ll inspect the part metadata, find the official datasheet if needed, update the Datasheet property, then compare symbol/footprint/pin details against the source and summarize any mismatches.

Completed the BNO086 part review and saved the detailed findings in BNO086 Part Review.
Summary: the symbol pin names/numbers and 28-pad LGA footprint match the official CEVA BNO08X/BNO086 datasheet. Flagged metadata issues: Datasheet URL uses an older CEVA domain, Manufacturer Name is set to BOSCH though the listed MPN manufacturer is CEVA Technologies, Package is missing, pin descriptions/types are mostly unspecified, and the description mentions SPI but omits I²C/UART support.

Provide a concise direct to the point best description for this part based from the datasheet. i don't need a very long but useless description.

Footprint cross-check
The footprint contains 28 SMD rectangular pads and matches the datasheet land pattern structure: side rows use 0.25 mm × 0.675 mm pads, top/bottom rows use 0.25 mm × 0.575 mm pads, with pad centers corresponding to the 3.8 mm × 5.2 mm LGA footprint geometry. The footprint outline is 3.8 mm × 5.2 mm and courtyard is 5.8 mm × 7.2 mm.
Mismatches / issues flagged
  1. Datasheet URL property is set but uses an older CEVA domain: current official URL found is https://www.ceva-ip.com/wp-content/uploads/BNO080_085-Datasheet.pdf. Existing URL may still redirect/resolve, but the current official host is preferable.
  2. Manufacturer Name property says BOSCH: datasheet notes Bosch Sensortec manufactures the physical device, but distributor/manufacturer listing for MPN BNO086 is CEVA Technologies, Inc. Consider changing manufacturer to CEVA Technologies, Inc. or adding Bosch in role/details if desired.
  3. Package property is missing: recommended value is 28-LGA (5.2x3.8) or 28-TFLGA Module.
  4. Pin Type / Pin Description properties are not populated: all schematic terminal Pin Type fields inspected are Unspecified; datasheet provides clear input/output/bidirectional/NC roles and descriptions.
  5. Description is mostly correct but incomplete: it says SPI output only, while datasheet supports I²C, SPI, and UART host interfaces.
Conclusion
The core symbol pin numbering/names and footprint pad count/geometry are consistent with the official BNO08X datasheet for BNO086. The main cleanup items are metadata quality: update the datasheet URL to the current official CEVA URL, manufacturer naming, package property, pin type/descriptions, and description interface coverage.
