Part review summary

I reviewed the available project data and the built-in part checks for M20-8900705.

Available part information in the project

Field	Status	Notes
MPN	Present	M20-8900705
Manufacturer	Missing	Review flags Manufacturer Name is not set

Official source found

I found the official Harwin product page:

https://www.harwin.com/products/M20-8900705

From the official search result text for that page:

Product family: 2.54 mm (.1") pitch horizontal pin header
Style: single row surface mount
Contacts: 7
Description snippet: 6.0 mm mating pin, 3.46 mm molding profile
Finish snippet: gold finish on contact area and termination

The same official result references:

Technical Drawing / Datasheet - M20-890.pdf

What I could verify against the project Symbol

Schematic contains 7 terminals.
Terminal numbers are 1, 2, 3, 4, 5, 6, 7.
This matches the official product page contact count of 7.

Footprint

From the footprint asset:

7 SMD pads
Pad names: 1-7
Pad pitch appears to be 2.54 mm from pad center spacing
Footprint is consistent with a right-angle SMT single-row header

Pin mapping consistency

Symbol numbering and footprint pad numbering are aligned 1:1
I found no numbering mismatch between symbol and footprint

Issues flagged

Project metadata issues

Issue	Severity
Manufacturer Name missing	Error
Datasheet property missing	Error
Project Part Type missing	Error

Symbol property completeness

Each terminal is missing these parametric symbol properties:

Pin Group
Pin Orientation
Section

These are warnings, not hard mismatches.

Mismatch assessment

Area	Result
MPN	OK
Pin count	OK
Symbol numbering	OK
Footprint pad count	OK
Symbol-to-footprint numbering	OK
Datasheet URL property	Missing
Manufacturer property	Missing
Project Part Type	Missing
Pin descriptions	Not available in current project data
Full dimensional cross-check to datasheet PDF	Not completed

Important limitation

I was able to find the official Harwin product page, but I was not able to retrieve the actual PDF contents within this run. Because of that, I could not fully verify:

exact mechanical dimensions from the datasheet drawing
official package naming as stated in the PDF
any per-pin functional descriptions beyond simple numbering
current/voltage/environmental specs directly from the datasheet document

So at this point I can confidently say:

the project is structurally consistent for a 7-position Harwin SMT right-angle header
there are no obvious symbol/footprint pin-count or numbering mismatches
the part metadata is incomplete and needs cleanup

Best next update

The most likely official datasheet target is the Harwin PDF referenced by the product page:

M20-890.pdf

If you want, I can turn this into a plan to:

add the official datasheet URL to the part properties
fill in the missing manufacturer and part-type properties
tighten the terminal metadata
then do a second-pass mismatch check once the PDF link is confirmed inside the project.

Add datasheet metadata

Clean terminal metadata
