How to read this profile
V51 records position count and pitch only; it does not publish PCIe A/B-side logical assignments, card-outline keying dimensions or motherboard routing.
Bounded dimensions
Only what the sources support
Source-scoped dimensions; not fabrication clearances
Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.
Documented examples; not a mating drawing or compatibility approval
Nominal contacts

Recorded variant and source limits
The card-edge form does not by itself establish PCIe generation, active lanes, bifurcation, electrical compliance, power budget or motherboard behavior.
Pitch and position count do not constitute a fabrication drawing, slot-compliance gauge or board-layout approval.
PICMG design-guide x1 reference slot: Source schematic contact identities A1-A18 / B1-B18. The two columns are schematic symbol sides, not a verified mating-face or solder-side view.
Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.
What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.
Unknowns stay unknown.
The card-edge form does not by itself establish PCIe generation, active lanes, bifurcation, electrical compliance, power budget or motherboard behavior.
Pitch and position count do not constitute a fabrication drawing, slot-compliance gauge or board-layout approval.
Page scope: Original V51 engineering boundary schematic; not to scale and not a PCIe logical pinout, slot gauge or manufacturing drawing.
Assessment 2026-10-22 · earliest scheduled source review 2027-01-04. This is a recorded-date assessment, not a live source check. Page-level independent review is not established by this panel.
Scoped support: Manufacturer series reference for the PCI Express x1 mechanical/contact-count form only.
Not established / limitations: Source-backed identification does not establish universal wiring, protocol generation, device compatibility, safe installation or fabrication approval.

Scoped support: Manufacturer-series context for PCIe x1/x4/x8 card-edge contact counts and 1.00 mm pitch only.
Not established / limitations: Pitch and position count do not establish PCIe generation, lane enablement, bifurcation, board layout, electrical compliance or fabrication approval.

Recorded evidence only. An inspection date, publisher label, source link or generated packet is not independent technical review, hardware testing, fabrication approval or a compatibility verdict.
