The Splice CAD KiCad plugin exports the connectors on your PCB into a Splice Project in one click — Tools → External Plugins → Export to Splice CAD. It detects each board header, reads pin functions from the netlist, and writes manufacturer/MPN to the BOM. Headers import into the Project Workflow as components; you assign the mating connectors and route conductors between them to complete the cable-harness document.

Splice CAD Export preview dialog: board summary, the J1–J8 connector checklist with manufacturer and MPN, and the per-pin signal table.

Details

  • Detection: connectors by reference prefix (J/CN/CON/P/X) and footprint pattern; mounting holes and non-plated pads filtered out.
  • Pin functions: read from the sibling .net netlist — signals (e.g. CAN_H) land on the correct pins; unconnected pins are NC.
  • Delivery: hands off to a running Splice CAD desktop app over localhost (offline, no API key), or POSTs to your account with an API key.
  • Stable IDs: node/pin IDs derive from each connector reference, so re-export reproduces the same shape.

Install

In KiCad's Plugin and Content Manager → Manage → Repositories, add:
