The search results did not include:

Pad XY positions in the PCB footprint
Pad sizes
Pad shapes
Pad layer definitions
Drill sizes or plated/non-plated status
Board outline / courtyard / fab / silkscreen dimensions
Text locations or dimensions
3D model offset, scale, rotation, or other metadata beyond the asset name D36V50F5.stp

So, based on the available project index, I can identify the footprint and enumerate its pads/pin names, but I cannot precisely describe the physical footprint geometry without access to the raw D36V50F5.kicad_mod contents.

Audit complete. The existing Datasheet property already links to Pololu’s official dimensional drawing, so no update was needed; pin names/count match, but Part Type is incorrectly “Diodes,” all pin types are unspecified, description/package metadata are missing, and the footprint silkscreen contains overlapping placeholders.

Full specifications, footprint verification limits, and recommended corrections are in D36V50F5 Part Information and Datasheet Audit.

D36V50F5 Part Information and Datasheet Audit

Audit scope

Reviewed project metadata, all 15 schematic terminals, footprint pad inventory and rendered footprint geometry, attached assets, the configured Datasheet property, and official Pololu product information for the D36V50F5.

Symbol and terminal audit

The symbol contains 15 terminals: 12 numbered electrical terminals and 3 mounting-hole terminals.

Table

Project pin(s)	Official function	Cross-check

3–6: GND_1 through GND_4	Ground, duplicated across connector rows	Pass
7–8: VIN_1, VIN_2	Input supply, 5.5 V to 50 V for D36V50F5	Pass

11: EN	Enable input; internal 100 kΩ pull-up to VIN; low below 1.2 V enters sleep, high above 1.35 V enables	Pass by name
12: PG	Open-drain power-good output; external pull-up required	Pass by name
MH1–MH3	Three mechanical mounting holes for #2 or M2 screws	Pass

Symbol issues

All terminal Pin Type fields are Unspecified. This is incomplete and weakens ERC. Recommended classifications:
- VOUT: Power Output
- GND: Power Input or Ground/Power
- VIN and VRP: Power Input (VRP is bidirectional in some use cases, but Power Input is the safer default for normal module use)
- EN: Input
- PG: Open Drain / Open Collector output
- MH1–MH3: Mechanical / passive, depending on available type choices
Pin descriptions are absent. Names are correct, but functional descriptions should explain duplicated power pins, VRP bypass behavior, EN thresholds/default pull-up, and PG open-drain behavior.
The symbol pin inventory and naming match the official module connections. Exact numeric ordering was compared with the modeled footprint inventory; no contradictory pin mapping was found in the available official drawing/product data.

Footprint audit

Confirmed matches

15 pads are present: 12 electrical through-hole connector pads and 3 mounting-hole pads.
Electrical connections are arranged as duplicated VOUT, GND, VIN, and VRP plus single EN and PG connections, consistent with Pololu's product documentation.
The connector pattern is intended for a 2.54 mm (0.1 in) grid.
Official connector drill diameter is 1.02 mm for 12 connector holes.
Official mounting-hole diameter is 2.2 mm for three holes, intended for #2 or M2 screws.
The rendered body outline is 25.4 mm square, consistent with the nominal 1 in × 1 in product size.
Footprint and STEP assets are present.

Verification limitations / risks

The structured layout inspection exposed pad identities but did not expose each pad's baked XY coordinate, copper diameter, drill diameter, plating, or layer set. Therefore, the exact 1.02 mm connector drills, 2.2 mm mounting drills, 2.54 mm pitch, and mounting-hole coordinates could not be numerically proven from the current project representation.
The footprint renderer did not display the pads in the flat preview even though all 15 pad nodes exist. This may be a rendering/indexing limitation, but it prevents visual confirmation of hole geometry.
Silkscreen includes overlapping placeholder/reference text (``, PS#, and PS**) at the same location. This is a footprint-quality issue and should be cleaned up before publication/use.
No courtyard/package metadata is set. The official assembled height is approximately 9.5 mm without optional headers.

Mismatches and recommended corrections

High priority

Change Part Type from Diodes to a regulator/power-supply-module classification.
Assign electrical Pin Type values instead of Unspecified, especially for VIN, VOUT, EN, and PG.
Numerically verify the raw footprint against Pololu's dimensional drawing: all pad coordinates, 1.02 mm connector drills, 2.2 mm mounting drills, 2.54 mm grid, and board/body datum orientation.

Medium priority

Add description: 5V, 5.5A step-down voltage regulator module, 5.5V–50V input.
Add package/mount metadata such as Through-hole module, 25.4 mm × 25.4 mm.
Add detailed pin descriptions, particularly EN and PG behavior and the VRP bypass function.
Remove overlapping placeholder/reference silkscreen text and retain a single readable reference/value scheme.

Informational

The configured Datasheet URL is official but is only the mechanical dimension drawing. Keeping it satisfies the existing property, but an additional product-page/resource link would better cover electrical behavior if the library supports another documentation property.
