Part Metadata Audit and Verification

Thought for 23 sec

I’ll audit the OV2640 part metadata, find or verify the official datasheet URL, then compare the symbol pins, footprint/pad count, and pin descriptions against the datasheet. I’ll put the detailed findings in a project file and keep the final summary concise.

Completed the part audit and created OV2640 Camera Board Part Audit.

Key result: the Datasheet URL was already present, the footprint has the correct 18 through-hole pad count, but the schematic symbol pin numbering is critically mismatched against the Waveshare 18-pin connector schematic—17 of 18 pins differ, with only GND on pin 18 matching. I also flagged naming issues: VSYNK → VSYNC, RET → RESET, and PWON → PWDN.

Fix all symbol pin numbers and names to match the Waveshare 18-pin datasheet. also convert the symbol to parametric style, and place each pin into the correct section based on the datasheet.

I’ll correct the terminal names and pin-number metadata to the Waveshare 18-pin connector order, then set parametric-symbol properties and section/group metadata so the symbol is organized by power, control, clock/sync, SCCB, and data bus.

Fixed the symbol to match the Waveshare 18-pin OV2640 Camera Board pinout.

Updated:

Pin names: RESET, PWDN, VSYNC, SIOC, SIOD, D2–D9, PCLK, XCLK, 3.3V, GND
Pin numbers: now match the Waveshare connector order exactly
Pin descriptions and electrical types
Parametric symbol metadata
Functional sections: Power, Ground, Control, Clock, Communication, and Data

Verification passed with no reported terminal/parametric review issues.

Footprint Review

The footprint contains 18 through-hole circular pads, matching the 18-pin camera board connector count.
Pad drill shown in footprint asset: approximately 1.100 mm; pad diameter 1.60 mm.
Pad pitch is 2.54 mm in two columns, matching the expected 2 × 9 camera board header style.
The footprint pad count is correct, but because the symbol terminal pin numbers are mapped incorrectly, a PCB using the current symbol would connect most signals to the wrong physical pads.

Mismatches / Issues Flagged

Critical symbol pin-number mismatch: 17 of 18 terminal pin assignments disagree with the Waveshare schematic pinout; only GND at pin 18 matches.
Terminal naming issues: VSYNK should be VSYNC; RET likely should be RESET; PWON likely should be PWDN.
Part Type is misleading: Library metadata says Raspberry Pi, but this is a camera module / sensor evaluation board, not a Raspberry Pi board.
BOM tool reports no parts added: This project behaves like a part/symbol project composed of terminals and footprint assets rather than a normal schematic assembly, so BOM metadata must be taken from the library/project part properties instead of schematic BOM output.
No schematic nets are defined: This is expected for a standalone part project, but it means ERC-style electrical connectivity checks are not meaningful here.

Recommended Corrections

Update terminal pin numbers and names to match the expected connector pinout table above.
Rename VSYNK → VSYNC, RET → RESET, and PWON → PWDN.
Update the Part Type metadata from Raspberry Pi to a more accurate value such as Sensor Evaluation Board or Camera Module if allowed by the part property schema.
Keep the 18-pad through-hole footprint, but revalidate pad numbering after symbol pin-number correction.

Verdict

The datasheet URL is already present, the footprint pad count matches the camera board connector, and key specs align with an OV2640 3.3 V camera module. However, the schematic symbol pin mapping is critically incorrect relative to the Waveshare 18-pin connector schematic and should be fixed before this library part is used in downstream designs.
