# Open Schematics Dataset

The largest dataset of electronic schematics and PCB layouts on the internet, built as an engineering reference for schematic and PCB layout work. It's a self-growing, autonomous dataset that continuously scans the web for new engineering designs and updates itself accordingly.

## Dataset Description

Each record corresponds to one schematic file and includes the raw source, rendered images, structured metadata, and all associated PCB files from the same project.

### Dataset Structure

| Field | Type | Description |
|---|---|---|
`schematic` |
string | Raw schematic file content (`.kicad_sch` , `.sch` , or `.SchDoc` ) |
`schematic_image` |
image | Rendered PNG of the schematic (None if unavailable) |
`pcb_files` |
list[string] | Raw content of PCB files (`.kicad_pcb` / `.pcb` ) from the same project |
`pcb_images` |
list[image] | Rendered PNGs of each PCB file, parallel to `pcb_files` (None per entry if unavailable) |
`components_used` |
list[string] | Component names extracted from library symbols (`.kicad_sch` only; None for other formats) |
`schematic_json` |
string | kiutils JSON representation of the schematic (`.kicad_sch` only; None otherwise) |
`schematic_yaml` |
string | kiutils YAML representation of the schematic (`.kicad_sch` only; None otherwise) |
`name` |
string | Source repository (`owner/repo` ) |
`description` |
string | Repository description |
`extensions_used` |
list[string] | File extensions present: schematic extension first, then unique PCB extensions (e.g. `[".kicad_sch", ".kicad_pcb"]` ) |

### Schematic formats included

`.kicad_sch`

— KiCad v5+ (primary format; includes JSON/YAML/components)`.sch`

— KiCad v4 legacy`.SchDoc`

— Altium Designer

### PCB filters applied

- PCB files larger than 10 MB are excluded (extreme outliers; affects <1% of files)
- Projects with more than 20 PCB files retain the 20 with the largest rendered image (highest detail), ranked by pixel area

## Dataset Creation

### Source Data

Schematics and PCB layouts collected from publicly available data from the web.

### Data Collection

Files were fetched and processed to extract:

- Raw schematic and PCB source files
- Rendered images (PNG/SVG → PNG)
- Structured metadata via
[kiutils](https://github.com/mvnmgrx/kiutils)(JSON/YAML) - Component lists from library symbol references

### Data Processing

- Empty
`.kicad_sch`

files (no library symbols or schematic symbols) are filtered out `.sch`

and`.SchDoc`

rows are included with raw text only; JSON/YAML/components are None when kiutils conversion is unavailable- Component names are extracted from
`libSymbols`

fields and deduplicated per library prefix `extensions_used`

is inferred from actual file paths on disk, not from YAML metadata fields

## Use Cases

**Circuit Design AI**: Training models to generate or understand electronic schematics** PCB Layout Understanding**: Learning the relationship between schematics and their physical PCB layouts** Component Recognition**: Identifying electronic components from schematic and PCB diagrams** Design Assistance**: Building tools to help engineers with circuit and PCB design** Multimodal Learning**: Paired schematic text + image + PCB text + image for cross-modal tasks** Documentation Generation**: Automatically generating documentation from schematics** Design Validation**: Training models to detect errors or suggest improvements** Educational Tools**: Creating interactive learning systems for electronics education

## Limitations

- JSON/YAML/components are only populated for
`.kicad_sch`

format (~85% of rows) - PCB images are unavailable for ~55% of PCB entries (no PNG or SVG rendered)
- Schematic images are unavailable for ~10% of rows
- Quality and complexity of designs vary significantly across projects
- Component naming conventions vary between projects and library sources
