Keep the drawing.
Recover the editable data.

We trace circuit schematics from paper, PDFs and images into editable KiCad documents for maintenance, repair, revision and future engineering work.

SCHEMATIC DIGITIZATION

Careful tracing, with uncertainties kept visible.

We recreate circuit symbols, wiring, reference designators, signal names and cross-page connections from the source drawing. Handwritten revisions can be included in the agreed scope.

Faded or missing information is marked for confirmation rather than silently treated as certain. Checking against a physical board is a separate service.
