Importing from Ultra Librarian

Overview

You can download schematic symbols, PCB footprints, and 3D models from Ultra Librarian and import them directly into tscircuit.

Downloading from Ultra Librarian

1. Visit Ultra Librarian.
2. Search for the manufacturer part number.
3. Select the footprint variant you need.
4. Click Download Now.
5. Sign in or create an Ultra Librarian account when prompted.
6. Choose the KiCad v5 or KiCad v6+ format and the CAD model.
7. Download and extract the ZIP file.

The extracted files include:

• the .kicad_mod file for the PCB footprint
• the .kicad_sym file for the schematic symbol
• the .stp file for the 3D model

Importing Ultra Librarian Components

Copy the files into your tscircuit project. Import them and pass them to the footprint, symbol, and cadModel props of a <chip />:

import stepUrl from "./CadModel.step"
import kicadMod from "./footprint.kicad_mod"
import kicadSym from "./symbol.kicad_sym"

export default () => {
  return (
    <board>
      <chip
        name="U1"
        footprint={kicadMod}
        symbol={kicadSym}
        cadModel={stepUrl}
      />
    </board>
  )
}

The .kicad_mod file provides the PCB footprint, while the .kicad_sym file provides the schematic symbol. The .stp file provides the 3D model for the 3D view and STEP exports.
