Part review summary
I reviewed the available project metadata, schematic terminals, PCB footprint structure, and the datasheet already linked in the project.
  • Datasheet URL was already set in the project properties, so no web search or property update was needed.
  • The part is identified as QAM-RX10-433 from RF SOLUTIONS.
  • Main issue found: the current part definition appears to expose only the 4-pin header, while the datasheet also shows a separate ANT connection point.

ANTNoNot visible in current footprint inspectionLikely missing from the part definition
Footprint cross-check
From the layout inspection:
What matches:
  • 4-pin header exists
  • Pin numbering/function mapping is consistent with the datasheet
  • Datasheet mechanical style is consistent with a through-hole 4-pin module on 2.54 mm pitch
What is missing or unclear:
  • The datasheet shows ANT at the far end of the module, opposite the 4-pin header.
  • The current footprint inspection shows no dedicated ANT pad/terminal.
  • I also did not see enough PCB-node detail to confirm the full body outline, exact hole sizes, or pin spacing implementation numerically inside the footprint.

Mismatches and flags

ItemStatusDetail
Symbol pin mapping for pins 1-4✅Matches datasheet
Footprint 4-pad presence✅Matches 4-pin header concept
ANT connection exposed❌Datasheet shows ANT separately, but the current symbol and footprint do not appear to expose it
Full pin descriptions on symbol terminals⚠️Functional names are present, but richer descriptions are not stored as terminal descriptions/properties
Package/body detail verification⚠️Overall module dimensions are known from datasheet, but not all footprint dimensions were visible in the layout inspection
Sensitivity spec consistency inside datasheet⚠️Datasheet overview and electrical table appear inconsistent for 433 MHz sensitivity
Recommended conclusion
The current part definition is mostly correct for the 4-pin header, but it appears incomplete because the datasheet indicates a separate ANT connection point that is not represented in the current symbol/footprint review.
Main flags
  • Missing ANT terminal/pad in the part definition
  • Terminal descriptions are minimal
  • Sensitivity value discrepancy exists within the datasheet itself
If you want, I can next:
  • update the part review into a concise correction checklist, or
  • check whether I can add an ANT terminal and improve the pin properties for you.
