Part Metadata Audit and Verification
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.
Thought for 20 sec
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.
Worked for 2 mins 40 sec
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:
VSYNKshould beVSYNC;RETlikely should beRESET;PWONlikely should bePWDN. - 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, andPWON→PWDN. - Update the Part Type metadata from
Raspberry Pito a more accurate value such asSensor Evaluation BoardorCamera Moduleif 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.
