Part Review and Datasheet Verification
Worked for 5 mins 30 sec
Completed the part review and created the detailed report: Part Review: SK6812MINIRGBW-NW-P6.
No critical pinout mismatch was found. The main flags are under-specified pin types/descriptions, a minor 3.5×3.7 vs 3.7×3.5 package-order wording difference, and footprint pad dimensions that could not be fully verified because the datasheet land-pattern drawing dimensions were not OCR-extracted.
Fix the pin types and add datasheet-based descriptions for all six terminals.
Thought for 5 sec
I’ll update the six terminal properties with datasheet-based pin types and descriptions, then re-read the symbol to verify the changes.
Worked for 22 sec
The descriptions are set; I’m normalizing the pin types to Flux’s standard values now.
Worked for 21 sec
Updated and verified all six terminal pin types and datasheet-based descriptions.
- NC: Not Connected
- GND: Ground
- DIN: Input
- VDD pins: Power In
- DOUT: Output
All descriptions now reflect the OPSCO datasheet functions.

Symbol review
The schematic symbol exposes six terminals and the pin numbers/functions match the datasheet. The left/right symbol arrangement is also reasonable: NC/GND/DIN on the left, DOUT/VDD pins on the right. No pin-number mismatches were found.
Potential improvements:
- The project terminal
Pin Typeproperties are allUnspecified; these could be refined to NC/passive or power/data input/output semantics if desired. - Pin descriptions are not populated as explicit
Pin Descriptionproperties. The designator names carry the function, but adding descriptions from the datasheet would improve library quality. NCshould be documented as “do not connect / cannot be used for circuit design,” not merely no-connect.
Footprint review
The footprint contains six top-layer rectangular pads with designators matching the six datasheet pins. Layout data reports the following computed pad positions and sizes:
Table
| Pad | Position | Size | Shape/layer |
|---|---|---|---|
| NC | x=-0.0017, y=+0.0011 | 0.00065 x 0.0014 | rectangle, Top |
| GND | x=-0.0017, y=0 | 0.00065 x 0.0014 | rectangle, Top |
| DIN | x=-0.0017, y=-0.0011 | 0.00065 x 0.0014 | rectangle, Top |
| VDD_2 | x=+0.0017, y=+0.0011 | 0.00065 x 0.0014 | rectangle, Top |
| DOUT | x=+0.0017, y=0 | 0.00065 x 0.0014 | rectangle, Top |
| VDD_1 | x=+0.0017, y=-0.0011 | 0.00065 x 0.0014 | rectangle, Top |
Flux reports these values with unit
mm, but the numeric magnitudes appear internally scaled; interpreted as meters converted to mm, they correspond to a plausible ±1.7 mm x ±1.1 mm 6-pad footprint with ~0.65 x 1.4 mm pads. The datasheet OCR did not extract the numerical land-pattern dimensions from the drawing, so I could not independently verify each pad dimension from text. The footprint topology and pin order appear consistent with the datasheet top-view pinout.Mismatches / flags
No critical pinout mismatch was found.
Flags and recommended cleanups:
- Datasheet URL is already set to a user-uploaded copy. This is acceptable, but if you prefer a public distributor URL, use the LCSC Rev. A/1 PDF URL above.
- Pin descriptions and pin types are under-specified in the Flux part; add explicit
Pin Descriptionand more specificPin Typevalues for library clarity. - The package/property metadata says description 3.5 x 3.7 mm, while the datasheet text states MINI package size 3.7 x 3.5 x 1.9 mm. This is likely just width/length ordering, not an electrical mismatch.
- Footprint pad dimensions could not be fully checked because the datasheet land-pattern drawing dimensions were not OCR-extracted; visually/topologically the six-pad arrangement matches.
