Cross-check: symbol and footprint vs datasheet Result

Datasheet propertyPresent
Pin countMatches at 96
Footprint mechanical styleAppears broadly consistent with datasheet dimensions and 96-pad architecture
Symbol pin mappingMajor mismatch
Symbol naming vs datasheetMajor mismatch
Manufacturing riskCritical
Critical mismatches found Pin mapping mismatches
The current symbol does not match the datasheet pinout. This is severe enough to cause incorrect boards.

What this implies

Table

RiskWhy it matters
Wrong power pinsVCC and GND are misassigned near the start of the symbol, which can create direct miswiring of supply rails
Wrong control pinsPWR_ON, RESET_N, and VUSB_DET appear offset
Wrong RF pinsANT and ANT_DET do not align to datasheet numbering
Reserved-pin violationDatasheet says pin 59 must be reserved / left open, but the symbol maps that region as ground-related
Schematic-to-footprint mismatch hazardEven if pad count is right, wrong pin numbers mean the PCB will route the wrong nets to the correct physical pads
Board failure riskHigh likelihood of non-booting module, damaged part, RF failure, or impossible bring-up
Footprint assessment

Table

ItemAssessment
Pad count96, consistent with datasheet
Package outlineAppears consistent with 26 mm x 16 mm class module
Edge pad geometryAppears consistent with 0.8 mm x 1.5 mm pads
Central pad geometryAppears consistent with 1.1 mm x 1.1 mm central pads
Pin 1 markerPresent in footprint asset
Final verdictFootprint looks plausible mechanically, but cannot be trusted in use until symbol pin numbering is corrected
Final verdict

Table

CategoryStatus
Datasheet availabilityGood
Metadata completenessGood enough for review
Symbol correctnessFail
Footprint mechanical plausibilityProbably OK
Overall manufacturing readinessNot safe
  • The biggest issue is not missing metadata.
  • The biggest issue is that the symbol pin-number mapping is critically wrong relative to the datasheet.
  • If this part is used as-is, it could cause incorrect ordering/use, manufacturing defects, or immediate board failure.
If you want, I can next check whether I’m able to fix the part project by correcting the symbol pin mapping and identifying exactly which terminals need renumbering.
