Schematic extractor
About the Schematic extractor PCB
Schematic extractor is an open source PCB design by D4NGYY, published on GitHub under the MIT license. It is a board, with 33 components from 12 distinct parts.
Other key parts include the 24C16 and S5933_PQ160. By type, the board carries 12 capacitors, 5 resistors and 2 ICs.
From the project
Reconstruct electrical topology from vector-PDF schematics — Components↔Nets graph, YOLO component detector, LLM tool-calling. Honest, measured F1 scores.
Reconstruct the electrical topology of a vector-PDF schematic — components, pins, and the nets that connect them — as a queryable Components↔Nets graph, exportable to SPICE / KiCad / JSON and answerable in natural language through an LLM tool-calling layer.
Legacy schematics (service manuals, CAD exports) are locked as pixels or vector strokes with no machine-readable connectivity. This project bridges them to the modern ecosystem: from a flat PDF to a graph you can simulate, version, and ask questions about.
