Review Summary
I reviewed the current part-project metadata, terminal set, footprint shape, and the linked Nordic datasheet. The Datasheet URL is already populated and points to the official Nordic PDF, so no web lookup or property update was needed. The verification flow I followed matches the recommended part-project datasheet sync process: confirm the datasheet URL first, then compare project metadata, pin count, terminal properties, and footprint against the datasheet

Manufacturer NameNordic SemiconductorDatasheet says Nordic Semiconductor ASAMinor mismatch
Manufacturer Part NumberNRF24L01P-MODULE-SMADatasheet identifies the IC as nRF24L01+Major mismatch
Package or Case CodeModuleDatasheet package is 20-pin QFN, 4 mm x 4 mm, with WLCSP also listedMajor mismatch

Temperature range-40 C to +85 C
PackageQFN20, 4 mm x 4 mm, 0.5 mm pitch
These values come directly from the linked Nordic datasheet
Pinout cross-check
The datasheet pinout for the IC has 20 pins: CE, CSN, SCK, MOSI, MISO, IRQ, multiple VDD/VSS pins, XC1/XC2, VDD_PA, ANT1, ANT2, IREF, and DVDD
Your current part project contains only 8 terminal components, each with a numeric designator and Pin Number set from 1 to 8. All of them currently have Pin Type: Unspecified, and none show pin descriptions, sections, pin groups, pin orientation, or sub-symbol data in the schematic data. That means the current symbol does not match the datasheet’s 20-pin device structure, and the terminal metadata is incomplete relative to the recommended part-project requirements
Footprint cross-check
The current layout contains only 8 pads in the footprint. The datasheet package is a 20-pin QFN 4 mm x 4 mm package, so an 8-pad footprint is not consistent with the linked datasheet package
Mismatches flagged

High-confidence mismatches

AreaWhat I foundWhy it is a mismatch
Pin countProject has 8 terminalsDatasheet device has 20 pins
Symbol completenessAll terminal pin types are Unspecified; no pin descriptions or sectioningDatasheet provides defined functions for all pins
FootprintProject has 8 padsDatasheet package is QFN20
MPNProject says NRF24L01P-MODULE-SMADatasheet is for nRF24L01+ IC, not clearly the SMA module
PackageProject says ModuleDatasheet package is QFN20 4x4 mm
DescriptionProject description refers to eval/module wordingLinked datasheet describes the bare transceiver IC
Likely root cause
This project appears to represent an 8-pin SMA module breakout/header rather than the bare nRF24L01+ IC. If that is true, then the current datasheet is for the wrong thing for symbol/footprint verification. In other words:
  • If you intended to model the bare Nordic IC, then the current symbol and footprint are incorrect.
  • If you intended to model the 8-pin RF module with SMA connector, then the current symbol/footprint may be directionally right, but the linked datasheet and several metadata fields are wrong for that module.
That distinction matters because the sync guidance requires exact pin-count matching and using the datasheet as the single source of truth for pin numbers and package data
Pin-description status
I could not validate module-level pin descriptions from the linked Nordic IC datasheet because the project only exposes 8 terminals while the datasheet describes the 20-pin silicon die/package. So the current terminal descriptions should be treated as not verified against the linked datasheet.
Bottom line What is correct
  • The Datasheet URL is already set and points to the official Nordic PDF.
  • The linked datasheet is valid for nRF24L01+ silicon.
What is not consistent
  • The project metadata looks like an SMA module/eval board, while the datasheet is for the bare transceiver IC.
  • The schematic symbol and footprint are 8-pin, while the datasheet package is 20-pin QFN.
  • Terminal metadata is incomplete: pin types and descriptions are not populated.
Recommended next step
Please confirm which part this project is supposed to represent:

Table

Intended partWhat should happen
Bare nRF24L01+ ICRebuild metadata, symbol, and footprint to match the 20-pin QFN datasheet
NRF24L01+ module with SMA/headerFind the module’s official datasheet or pinout document, then re-verify metadata, 8-pin symbol, and footprint against that module document
If you want, I can do the next step for you:
  • Option A: convert this into a correct bare nRF24L01+ IC part
  • Option B: keep it as an 8-pin SMA module and help locate/use the correct module-level datasheet or vendor pinout for a proper re-check
