Features

A VS Code viewer for KiCad schematic and PCB files. Supports both viewing single files, as well as diffing two files against each other.

Single files

The extension registers itself as the default viewer for .kicad_sch and .kicad_pcb files. You can manually switch back to the text editor/to the viewer again using the View: Reopen Editor With... action.

Viewing a single schematic: single schematic view

Viewing a single PCB: single pcb view

Diffing two files

The extension registers itself as the default diff viewer for .kicad_sch and .kicad_pcb files. This means that any time a file comparison is triggered (e.g. via Compare against previous revision), the visual diff view is used instead. As for the single file viewer, switching back to the text editor can be done using the View: Reopen Editor With... action.

Comparing two schematic revisions: schematic diff view

Comparing two PCB revisions: pcb diff view

Requirements

  • KiCad 9.0 installed. Default CLI path is C:\Program Files\KiCad\9.0\bin\kicad-cli.exe; override via the kicadViewer.kicadCliPath setting.
