Part Datasheet Review
Thought for 1 min 31 sec
I’ll inspect the existing part metadata, look for an official datasheet if one isn’t already linked, update that property if needed, then compare symbol/footprint/pin details against the datasheet.

Part Datasheet Cross-Check: XL-1615RGBC-WS2812B-S
Date: 2026-07-20 Existing Flux part metadata and schematic terminals.
Completed the part review and saved the detailed findings in Part Datasheet Cross-Check: XL-1615RGBC-WS2812B-S. The existing Datasheet URL property was already set, so I did not overwrite it; the symbol pinout and footprint match the datasheet, with flagged metadata issues around the “10V” description wording, unspecified pin types/descriptions, missing explicit manufacturer metadata, and oversized footprint text.
Suggested next steps:
- Update the part description to clarify VDD is 3.5–5.5 V and 10 V is DOUT withstand.
- Add manufacturer, pin descriptions, and specific pin types.
- Clean up/hide oversized silkscreen text in the footprint.

Datasheet pinout
Table
| Pin | Name | Datasheet function | Expected physical location with package center origin and emitting face up |
|---|---|---|---|
| 1 | GND | Signal ground and power ground | Lower-left |
| 2 | DIN | Display data input | Lower-right |

Schematic symbol cross-check
Observed schematic terminals:
Table
| Terminal | Pin Number property | Pin Type property | Symbol position | Datasheet result |
|---|---|---|---|---|
| GND | 1 | Unspecified | Left/lower | Pin number and broad location match |
| DIN | 2 | Unspecified | Right/lower | Pin number and broad location match |
| VDD | 3 | Unspecified | Right/upper | Pin number and broad location match |
| DOUT | 4 | Unspecified | Left/upper | Pin number and broad location match |
Symbol findings
- Pin numbering and signal names match the datasheet.
- The symbol arrangement matches the physical pad quadrants: GND lower-left, DIN lower-right, VDD upper-right, DOUT upper-left.
- Mismatch / metadata gap: pin descriptions are not populated in the inspected terminal properties.
- Mismatch / metadata gap: all terminal Pin Type values are
Unspecified. Recommended values would be: GND = Ground or Power, VDD = Power, DIN = Input, DOUT = Output.
Footprint cross-check
Observed footprint asset includes these KiCad pads:
Table
| Pad | Project pad name | KiCad coordinate | Size | Datasheet expected |
|---|---|---|---|---|
| 1 | GND | (-0.625, +0.475) in KiCad asset; rendered as lower-left after coordinate transform | 0.45 x 0.65 mm | Match |
| 2 | DIN | (+0.625, +0.475) in KiCad asset; rendered as lower-right after coordinate transform | 0.45 x 0.65 mm | Match |
| 3 | VDD | (+0.625, -0.475) in KiCad asset; rendered as upper-right after coordinate transform | 0.45 x 0.65 mm | Match |
| 4 | DOUT | (-0.625, -0.475) in KiCad asset; rendered as upper-left after coordinate transform | 0.45 x 0.65 mm | Match |
Datasheet land pattern values:
- Pad size: 0.45 x 0.65 mm.
- Inner horizontal gap: 0.80 mm.
- Vertical gap between pad rows: 0.30 mm.
- Inferred pad center offsets: x = +/-0.625 mm, y = +/-0.475 mm.
Footprint findings
- Pad count, pad dimensions, pad center locations, and pin mapping match the datasheet land pattern.
- Fab outline is 1.6 x 1.5 mm, matching the package body.
- The footprint includes a pin-1 marker near the GND side, consistent with the datasheet.
- Minor issue: the footprint contains large 1.27 mm reference/value text at the package origin. For this very small LED package, those labels are not manufacturable/legible on silkscreen at the component body and should usually be hidden or moved for a production footprint.
- Possible issue: the footprint asset name omits hyphens (
XL1615RGBCWS2812BS.kicad_mod), but the functional mapping is correct.
Mismatches and recommended cleanup
- Description voltage ambiguity: the project description ends with
10V, but the part is not a 10 V supply LED. Datasheet VDD is 3.5-5.5 V; the 10 V value refers to output port withstand voltage. Recommended description wording:SMD-4P 1.6 x 1.5 x 0.6 mm RGB addressable LED with built-in WS2812B-compatible IC; VDD 3.5-5.5 V; DOUT withstand 10 V; RoHS; -40 to +85 C. - Manufacturer metadata gap: manufacturer is not explicit in the inspected terminal properties. Recommended Manufacturer Name:
XINGLIGHT. - Pin metadata gaps: terminal Pin Description and specific Pin Type values are missing/unspecified.
- Silkscreen text sizing: reference/value text is too large for a 1.6 x 1.5 mm package if emitted on silkscreen; use hidden text or external assembly/fab labels.
Overall result
The core electrical pinout and PCB footprint are consistent with the datasheet. The main issues are metadata quality problems rather than pad geometry errors: voltage wording should distinguish VDD from output withstand voltage, manufacturer/height/pin descriptions should be added, and pin types should be made specific.
