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 License This dataset is released under the Creative Commons Attribution 4.0 International CC-BY-4.0 license.
