Part Metadata Review and Update

Thought for 4 mins

Done - I reviewed the part project and updated the missing Datasheet URL to the official Lumex PDF.

What I found Current part metadata

Table

Datasheet URL	Added: `https://www.lumex.com/datasheet/files/LCD-S401M16KR.pdf`
Package / Case Code	Missing as a project property

Key specs from the official datasheet / distributor listing

Table

Spec	Value
Description	4 digit, 0.17 in, 7-segment custom LCD panel
Display type	TN - Twisted Nematic
Display mode	Reflective
Backlight	Without backlight
Viewing direction	6:00
Drive method	1/4 duty, 1/3 bias
Operating voltage	3.0 V AC
Operating temperature	0 C to 50 C
Storage temperature	0 C to 50 C
Pin count	12 pins
Character height	4.42 mm
Outline	20.32 mm x 10.16 mm x 2.80 mm
Viewing area	17.92 mm x 5.28 mm

The part-project sync guidance says the datasheet should be treated as the source of truth, the pin count must match exactly, and pin metadata should be populated from the datasheet rather than left generic

Cross-check results 1) Schematic symbol

Pass: the symbol has 12 terminals, which matches the datasheet's 12 pins.
Mismatch / incomplete data: all terminals are currently just generic numbered terminals with:
- no pin names
- no pin descriptions
- all pin types set to Bi-Directional
That means the symbol is structurally the right size, but semantically incomplete versus the datasheet. The sync rules specifically call for exact datasheet-derived pin numbers, names, and functions rather than generic placeholders

2) Footprint

Pass: the footprint has 12 pads, so the pad count matches the symbol and datasheet.
Likely okay mechanically: the attached footprint/3D model assets exist, and the part dimensions line up with the published package/module dimensions.
Limitation: I could not extract the exact pad numbering/order or the full pin-function table from the PDF automatically, so I could not conclusively verify pad-to-pin naming/orientation mapping.

3) Pin descriptions

Mismatch: there are currently no pin descriptions in the part project.
Mismatch: all pins are marked Bi-Directional, which is unlikely to be correct for an LCD glass module because these pins usually have specific COM/SEG drive roles rather than generic bidirectional behavior.
Per the sync workflow, missing pin names/descriptions/types should be treated as incomplete metadata that needs to be filled from the datasheet pin table

Summary of issues to flag

Table

Area	Result	Notes
Datasheet URL	Fixed	Official Lumex PDF added
Pin count	Good	12 symbol terminals / 12 footprint pads / 12 datasheet pins
Pin names	Missing	Symbol terminals are unnamed generics
Pin descriptions	Missing	No functional descriptions present
Pin types	Likely wrong	All set to Bi-Directional
Package property	Missing	Should be added as a project property
Manufacturer property	Missing	Should be added as a project property

Recommended next step

The remaining gap is the exact 12-pin function table. Once that is extracted cleanly from the datasheet, I can finish the audit by:

naming each terminal,
setting correct pin descriptions,
assigning more accurate pin types,
and verifying footprint pad numbering against the symbol.

If you want, I can do that next and populate the missing pin metadata directly.

Populate missing pin metadata
