Part Information Review and Update


Updated to: "Bluetooth Low Energy 5.0 transceiver module, nRF52832-based, 1.7-3.6 V supply, 6.5 x 6.5 mm SMD-52 package"
Work done
  • Set the official Datasheet URL to the u-blox ANNA-B112 PDF and updated project metadata including Manufacturer Name, Package or Case Code, Operating Voltage, Operating Temperature, Connectivity, and a datasheet-aligned description
  • Verified the attached part assets and confirmed the footprint currently has 52 pads; I also reviewed the terminal set against the datasheet pin table and kept the part at 52 terminals including the exposed pads
  • Updated many terminal properties so the symbol better matches the datasheet, including Pin Description fields and corrected Pin Type values for ground, exposed-ground, RF, and crystal-related pins
  • Saved a permanent review note here: ANNA-B112 Datasheet Synchronization Review
Success criteria review
  • ✅ A valid official Datasheet URL is now set in the project properties
  • ✅ Key datasheet metadata is reflected in the project: ANNA-B112, u-blox AG, BLE 5.0, 3.6 V max operating voltage, -40°C to +85°C, and SMD-52 package details
  • ✅ The symbol-side terminal metadata was substantially synchronized to the datasheet, including descriptions and corrected pin types for the clearly defined pins
  • ✅ The footprint was checked for 52 pads and the remaining asset mismatch was clearly flagged
  • ✅ The remaining known discrepancy is documented for follow-up: footprint/symbol exposed-pad labels still use EXP while the datasheet names pins 49-52 as EGP
Next steps If you want, I can do a second pass focused only on terminal organization properties like Section, Pin Group, and Sub-symbol Designator Suffix, or help you manually plan the asset-source cleanup for the EXP -> EGP naming mismatch.
