Part Information Review and Update

Thought for 1 min 4 sec

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.

Datasheet pin / connection cross-check

Table

Datasheet connection	Present in symbol	Present in footprint	Notes
Pin 1 Supply Voltage	Yes	Yes	Good
Pin 2 Data Output	Yes	Yes	Good
Pin 3 Data Output	Yes	Yes	Good
Pin 4 Ground	Yes	Yes	Good
ANT	No	Not visible in current footprint inspection	Likely missing from the part definition

Footprint cross-check

From the layout inspection:

The footprint currently contains 4 pads:

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.

Key specs from the datasheet

Table

Spec	Value
Receiver type	AM Superheterodyne
Frequency	433.92 MHz
Supply voltage	3.5 V to 5.5 V DC
Nominal supply	5 V
Supply current	6 mA typ
Data rate	10 Kbps
Turn-on time	25 ms min, 30 ms typ
Operating temperature	-25 C to +85 C
Sensitivity	Datasheet reports -108 dBm @ 433 MHz in electrical characteristics; overview text also mentions -123 dBm @ 433 MHz

Mismatches and flags

Table

Item	Status	Detail
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.
