Eugene Mikhantyev 7d50fa1d4c style: apply Prettier formatting to TS/JS/JSON/MD files
Add Prettier as a dev dependency with .prettierrc.json config and
.prettierignore. Hook added via mirrors-prettier in pre-commit config.
All TypeScript, JSON, Markdown, and YAML files auto-formatted.

Datasheet Management Tools

Added in: v2.2.0-alpha

Two tools for managing component datasheets using LCSC part numbers. Datasheet URLs are constructed directly from LCSC numbers -- no API key or network requests required.


Tools Reference

enrich_datasheets

Scans a KiCAD schematic and fills in missing Datasheet URLs for components that have an LCSC part number set.

How it works:

For every placed symbol that has:

  • An LCSC property set (e.g., (property "LCSC" "C123456"))
  • An empty or missing Datasheet field

The tool sets the Datasheet field to: https://www.lcsc.com/datasheet/C123456.pdf

The URL is then visible in KiCAD's footprint browser, symbol properties dialog, and any tool that reads the standard Datasheet field.

Parameters:

Parameter Type Required Default Description
schematic_path string Yes -- Path to the .kicad_sch file to enrich
dry_run boolean No false Preview changes without writing to disk

Returns:

  • Number of components updated
  • Number already set (skipped)
  • Number without LCSC number
  • Details of each updated component (reference, LCSC number, URL)

Example:

Enrich datasheets for all components in ~/Projects/MyBoard/MyBoard.kicad_sch

Use dry_run=true to preview what would change:

Preview datasheet enrichment for ~/Projects/MyBoard/MyBoard.kicad_sch with dry run enabled.

get_datasheet_url

Get the LCSC datasheet URL for a single component by LCSC number.

Parameters:

Parameter Type Required Description
lcsc string Yes LCSC part number, with or without "C" prefix (e.g., "C179739" or "179739")

Returns:

  • Datasheet PDF URL
  • Product page URL

Example:

Get the datasheet URL for LCSC part C179739.

Workflow

Adding Datasheets to a Design

  1. Add components with LCSC numbers -- When placing components from JLCPCB libraries or manually setting the LCSC property, each component gets an LCSC part number
  2. Run enrich_datasheets -- Scans all components and fills in any missing Datasheet URLs
  3. Verify in KiCAD -- Open the schematic in KiCAD and check that Datasheet fields are populated. Double-clicking a component shows the URL in its properties

Integration with JLCPCB Workflow

These tools complement the JLCPCB integration:

  1. Use search_jlcpcb_parts to find components
  2. Place components with LCSC numbers from the search results
  3. Run enrich_datasheets to auto-populate datasheet URLs
  4. Use export_bom to generate a BOM with datasheet links

Notes

  • The datasheet URL format (https://www.lcsc.com/datasheet/<LCSC#>.pdf) works for the vast majority of LCSC parts
  • No network request is made -- the URL is constructed from the part number alone
  • Components without an LCSC property are skipped silently
  • Components that already have a Datasheet URL set are not overwritten
