Use LCSC for **production sourcing** (assembled boards from JLCPCB\u002FPCBWay). DigiKey\u002FMouser are for prototyping. For BOM management and export workflows, see `bom`.\n\n## Key Differences from DigiKey\u002FMouser\n\n- **No API key needed** — jlcsearch community API is free and open\n- **Lower prices** — especially for passives and Chinese-manufactured ICs\n- **JLCPCB integration** — same LCSC part numbers used in JLCPCB assembly BOMs\n- **Direct PDF downloads** — LCSC's CDN (wmsc.lcsc.com) serves datasheets without bot protection\n- **Low MOQ** — many parts available in quantities as low as 1\n- **Warehouses** — Shenzhen (JS), Zhuhai (ZH), Hong Kong (HK)\n- **Website**: `https:\u002F\u002Fwww.lcsc.com`\n\n## LCSC Part Numbers\n\nFormat: `Cxxxxx` (e.g., `C14663`). This is the universal identifier across both LCSC and JLCPCB. Use it for:\n- Direct ordering on LCSC\n- BOM matching in JLCPCB assembly (see `jlcpcb` skill)\n- Cross-referencing between platforms\n\n## Component Search\n\nUse `search_lcsc.py` to search LCSC and JLCPCB for electronic components, check live stock, inspect pricing tiers, identify basic vs. extended parts, and fetch parametric attributes. **No API key required.**\n\n```bash\n# Search by keyword or description\npython3 \u003Cskill-path>\u002Fscripts\u002Fsearch_lcsc.py \"tactile switch\"\n\n# Search for basic parts only (no JLCPCB extended loading fees)\npython3 \u003Cskill-path>\u002Fscripts\u002Fsearch_lcsc.py \"0805 100R\" --basic\n\n# Filter by package\u002Ffootprint and stock\npython3 \u003Cskill-path>\u002Fscripts\u002Fsearch_lcsc.py \"red led\" --package 0805 --in-stock\n\n# Inspect full component details (manufacturer, datasheet URL, price breaks, parametric attributes)\npython3 \u003Cskill-path>\u002Fscripts\u002Fsearch_lcsc.py \"C318884\" --details\n\n# Output machine-readable JSON (for scripts and agent workflows)\npython3 \u003Cskill-path>\u002Fscripts\u002Fsearch_lcsc.py \"ME2108\" --limit 5 --json\n\n# Sort results by price or stock\npython3 \u003Cskill-path>\u002Fscripts\u002Fsearch_lcsc.py \"microcontroller STM32\" --sort price\n\n# Parametric category search (rows carry package, stock, price and attributes)\npython3 \u003Cskill-path>\u002Fscripts\u002Fsearch_lcsc.py \"STM32\" --category microcontrollers\n```\n\nThe script:\n- Queries the free `jlcsearch` community API for the search, then enriches from LCSC's direct product-detail endpoint (manufacturer, datasheet URL, price breaks) for exact `Cxxxxx` queries and for every hit shown with `--details` — one extra request per hit, 0.5s apart. If jlcsearch has no row for a `Cxxxxx` code, the direct lookup is the fallback.\n- Formats results into a clean terminal table highlighting `LCSC #`, `MPN`, `Package`, `Basic\u002FExt` status, `Stock`, `Price`, and `Description`\n- Supports `--basic` filtering to optimize PCB assembly BOM costs for JLCPCB manufacturing\n- Supports `--json` for automated BOM enrichment and agent workflows\n\n## jlcsearch API Reference\n\nThe jlcsearch community API is the recommended way to search LCSC. **No authentication required.**\n\n**Base URL:** `https:\u002F\u002Fjlcsearch.tscircuit.com`\n\n### General Search\n\n```\nGET \u002Fapi\u002Fsearch?q=\u003Cquery>&limit=20&full=true\n```\n\nParameters:\n- `q` — search query (matches MPN, LCSC code, or description keywords)\n- `package` — optional footprint filter (e.g., `0402`)\n- `limit` — max results (default 100)\n- `full` — accepted but no longer adds fields (the former `extra` block is gone, see below)\n\n### Category-Specific Search\n\n```\nGET \u002Fresistors\u002Flist.json?search=10k+0402\nGET \u002Fcapacitors\u002Flist.json?search=100nF+0402\nGET \u002Fmicrocontrollers\u002Flist.json?search=STM32\nGET \u002Fvoltage_regulators\u002Flist.json?search=3.3V\n```\n\n### Response Format\n\nGeneral search returns `{\"components\": [...]}`. As of 2026-09 each hit carries only these fields — the `extra` block (manufacturer, datasheet URL, per-warehouse stock, attributes, price breaks) is no longer returned, even with `full=true`:\n\n```json\n{\n  \"lcsc\": 318884,\n  \"mfr\": \"TS-1187A-B-A-B\",\n  \"package\": \"SMD-4P,5.1x5.1mm\",\n  \"is_basic\": true,\n  \"is_preferred\": false,\n  \"description\": \"-30℃~+85℃ 1.5mm 1.6N ... SMD-4P,5.1x5.1mm Tactile Switches ROHS\",\n  \"stock\": 1683297,\n  \"price\": 0.0197\n}\n```\n\nKey fields:\n- `lcsc` — numeric LCSC ID (without \"C\" prefix); prepend `C` for the LCSC code\n- `mfr` — manufacturer part number (no manufacturer name)\n- `is_basic` — `true` if JLCPCB basic part (no setup fee); `is_preferred` — JLCPCB preferred extended part\n- `stock` \u002F `price` — JLCPCB assembly stock and unit price (USD)\n\nCategory endpoints return `{\"\u003Ccategory>\": [...]}` — keyed by the category name, **not** `components`. Rows differ from the general search: `price1` instead of `price`, `in_stock`, an empty `description`, parametric columns (e.g. `resistance`, `cpu_core`), and `attributes` as a JSON **string**:\n\n```json\n{\"resistors\": [{\"lcsc\": 25804, \"mfr\": \"0603WAF1002T5E\", \"description\": \"\", \"stock\": 37165617,\n  \"price1\": 0.000842857, \"in_stock\": true, \"package\": \"0603\", \"resistance\": 10000,\n  \"is_basic\": true, \"is_preferred\": false,\n  \"attributes\": \"{\\\"Resistance\\\":\\\"10kΩ\\\",\\\"Power(Watts)\\\":\\\"100mW\\\",\\\"Tolerance\\\":\\\"±1%\\\"}\"}]}\n```\n\n### LCSC Direct Product Detail (enrichment)\n\nFor manufacturer, datasheet URL and price breaks, query LCSC's own endpoint by `Cxxxxx` code — no auth, JSON, `code: 200` on success:\n\n```\nGET https:\u002F\u002Fwmsc.lcsc.com\u002Fftps\u002Fwm\u002Fproduct\u002Fdetail?productCode=C318884\n```\n\nUseful `result` fields: `productModel` (MPN), `brandNameEn` (manufacturer), `pdfUrl` (direct datasheet PDF), `encapStandard` (package), `productIntroEn` \u002F `productDescEn` (description), `stockNumber` (LCSC stock), `productPriceList[]` (`ladder` = min qty, `usdPrice`). `provider_lcsc.search_lcsc_direct()` wraps this and normalizes the result to the jlcsearch dict shape (`extra.number`, `extra.mpn`, `extra.manufacturer.name`, `extra.datasheet.pdf`, ladder list in `price`); `search_lcsc.py` uses it for `Cxxxxx` enrichment and as the fallback when jlcsearch has no row.\n\n### Rate Limits\n\nNeither API documents rate limits, but be respectful — use delays of 0.5s between calls.\n\n## Datasheet Download & Sync\n\nLCSC's CDN serves datasheet PDFs directly — no bot protection, no special headers needed. This makes LCSC a reliable datasheet source alongside DigiKey.\n\n### Datasheet Directory Sync\n\nUse `sync_datasheets_lcsc.py` to maintain a `datasheets\u002F` directory alongside a KiCad project. Same workflow and `manifest.json` format as the DigiKey and Mouser skills. **No API key required.**\n\n```bash\n# Sync datasheets for a KiCad project\npython3 \u003Cskill-path>\u002Fscripts\u002Fsync_datasheets_lcsc.py \u003Cfile.kicad_sch>\n\n# Preview what would be downloaded\npython3 \u003Cskill-path>\u002Fscripts\u002Fsync_datasheets_lcsc.py \u003Cfile.kicad_sch> --dry-run\n\n# Retry parts a previous run failed at LCSC\npython3 \u003Cskill-path>\u002Fscripts\u002Fsync_datasheets_lcsc.py \u003Cfile.kicad_sch> --force\n\n# Custom output directory\npython3 \u003Cskill-path>\u002Fscripts\u002Fsync_datasheets_lcsc.py \u003Cfile.kicad_sch> -o .\u002Fmy-datasheets\n\n# Parallel downloads (3 workers)\npython3 \u003Cskill-path>\u002Fscripts\u002Fsync_datasheets_lcsc.py \u003Cfile.kicad_sch> --parallel 3\n\n# Batch mode — sync from a plain MPN list (no KiCad project required)\npython3 \u003Cskill-path>\u002Fscripts\u002Fsync_datasheets_lcsc.py --mpn-list mpns.txt --output .\u002Fdatasheets\n```\n\n**MPN-list batch mode** — when you have a list of MPNs but no\nKiCad project to point at. One MPN per line; blank lines and `#`\ncomments (full-line and inline) are skipped; generic values are filtered\nvia `is_real_mpn()` and de-duplicated. Output defaults to `.\u002Fdatasheets\u002F`\nin the current working directory when `--output` is omitted.\n\nThe script:\n- **Runs the kicad schematic analyzer** to extract components, MPNs, and LCSC codes\n- **Searches by LCSC code or MPN** (an MPN from the Value field matches its family); a part with only another distributor's PN is skipped\n- **Prefers LCSC code** for search (exact match) — falls back to MPN keyword search\n- **Falls back to wmsc.lcsc.com API** when jlcsearch has no results, or a hit has no datasheet URL, for an LCSC code (Cxxxxx)\n- **Downloads from LCSC CDN** — direct PDF URLs, no bot protection\n- **Writes `manifest.json` manifest** — same format as DigiKey\u002FMouser skills\n- **Verifies PDF content** — checks MPN, manufacturer, and description keywords\n- **Rate-limited** — 0.5s between API calls (configurable with `--delay`)\n- **Saves progress incrementally** — safe to interrupt\n\n### Single Datasheet Download\n\nUse `fetch_datasheet_lcsc.py` for one-off downloads.\n\n```bash\n# Search by MPN\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py --search \"GRM155R71C104KA88D\" -o datasheet.pdf\n\n# Search by LCSC code\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py --search \"C14663\" -o datasheet.pdf\n\n# Direct URL download\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py \"https:\u002F\u002Fwmsc.lcsc.com\u002F...\" -o datasheet.pdf\n\n# JSON output\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py --search \"C14663\" --json\n```\n\nThe script:\n- **OS-agnostic** — uses `requests` → `urllib` → `playwright` fallback chain (no wget\u002Fcurl)\n- **Refuses another part** — a `--search` hit that is a different part is not downloaded (exit 2); a family match is accepted\n- **Validates PDF headers** — rejects HTML error pages\n- **Falls back to alternative manufacturer sources** when LCSC URL fails\n- **Exit codes**: 0 = success, 1 = download failed, 2 = search\u002FAPI error\n- **Dependencies**:\n  - `pip install requests` (recommended; urllib fallback works fine for LCSC)\n  - `pip install playwright && playwright install chromium` (optional; rarely needed for LCSC)\n\n## LCSC Official API (Requires Approval)\n\n**Base URL:** `https:\u002F\u002Fips.lcsc.com`. Requires API key + signature authentication. Contact `support@lcsc.com` for access. Rarely needed — jlcsearch covers most use cases.\n\n## Web Search Fallback\n\nIf the jlcsearch API is unavailable, search LCSC by fetching the website directly:\n\n```\nhttps:\u002F\u002Fwww.lcsc.com\u002Fsearch?q=\u003Cquery>\n```\n\n## Cross-Referencing & Missing Equivalents\n\nLCSC part numbers are specific to the LCSC\u002FJLCPCB ecosystem. Use the `mfr` field (MPN) to cross-reference on DigiKey\u002FMouser.\n\nWhen an MPN has no exact LCSC match:\n1. Search by key parameters (e.g., \"100nF 0402 X7R 16V\")\n2. Look for pin-compatible alternatives from Chinese manufacturers\n3. Verify specs and footprint match — pad dimensions can vary even within the same package size\n4. As a last resort, mark as \"consigned\" and source separately\n\n## Tips\n\n- `is_basic` field matters — JLCPCB basic parts have no setup fee; extended parts cost $3 each\n- jlcsearch `stock` is JLCPCB assembly stock; the wmsc detail's `stockNumber` is LCSC's own stock — the two differ\n- MOQ and order multiples are no longer in the jlcsearch response — check the LCSC product page before ordering\n- Datasheet quality varies for Chinese manufacturers — cross-reference MPN on DigiKey for better docs\n","# LCSC Electronics — Component Search, Datasheets & Ordering\n\n## Related Skills\n\n| Skill | Purpose |\n|-------|---------|\n| `kicad` | Schematic analysis — extracts MPNs for part lookup |\n| `bom` | BOM management — orchestrates sourcing across distributors |\n| `jlcpcb` | PCB assembly — shares the same parts library |\n| `spice` | Uses LCSC parametric data for behavioral SPICE models (no auth needed) |\n\nLCSC is JLCPCB's sister company — they share the same parts library and `Cxxxxx` part numbers.

One MPN per line; blank lines and `#`\ncomments (full-line and inline) are skipped; generic values are filtered\nvia `is_real_mpn()` and de-duplicated. Output defaults to `.\u002Fdatasheets\u002F`\nin the current working directory when `--output` is omitted.\n\nThe script:\n- **Runs the kicad schematic analyzer** to extract components, MPNs, and LCSC codes\n- **Searches by LCSC code or MPN** (an MPN from the Value field matches its family); a part with only another distributor's PN is skipped\n- **Prefers LCSC code** for search (exact match) — falls back to MPN keyword search\n- **Falls back to wmsc.lcsc.com API** when jlcsearch has no results, or a hit has no datasheet URL, for an LCSC code (Cxxxxx)\n- **Downloads from LCSC CDN** — direct PDF URLs, no bot protection\n- **Writes `manifest.json` manifest** — same format as DigiKey\u002FMouser skills\n- **Verifies PDF content** — checks MPN, manufacturer, and description keywords\n- **Rate-limited** — 0.5s between API calls (configurable with `--delay`)\n- **Saves progress incrementally** — safe to interrupt\n\n### Single Datasheet Download\n\nUse `fetch_datasheet_lcsc.py` for one-off downloads.\n\n```bash\n# Search by MPN\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py --search \"GRM155R71C104KA88D\" -o datasheet.pdf\n\n# Search by LCSC code\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py --search \"C14663\" -o datasheet.pdf\n\n# Direct URL download\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py \"https:\u002F\u002Fwmsc.lcsc.com\u002F...\" -o datasheet.pdf\n\n# JSON output\npython3 \u003Cskill-path>\u002Fscripts\u002Ffetch_datasheet_lcsc.py --search \"C14663\" --json\n```\n\nThe script:\n- **OS-agnostic** — uses `requests` → `urllib` → `playwright` fallback chain (no wget\u002Fcurl)\n- **Refuses another part** — a `--search` hit that is a different part is not downloaded (exit 2); a family match is accepted\n- **Validates PDF headers** — rejects HTML error pages\n- **Falls back to alternative manufacturer sources** when LCSC URL fails\n- **Exit codes**: 0 = success, 1 = download failed, 2 = search\u002FAPI error\n- **Dependencies**:\n  - `pip install requests` (recommended; urllib fallback works fine for LCSC)\n  - `pip install playwright && playwright install chromium` (optional; rarely needed for LCSC)\n\n## LCSC Official API (Requires Approval)\n\n**Base URL:** `https:\u002F\u002Fips.lcsc.com`. Requires API key + signature authentication. Contact `support@lcsc.com` for access. Rarely needed — jlcsearch covers most use cases.\n\n## Web Search Fallback\n\nIf the jlcsearch API is unavailable, search LCSC by fetching the website directly:\n\n```\nhttps:\u002F\u002Fwww.lcsc.com\u002Fsearch?q=\u003Cquery>\n```\n\n## Cross-Referencing & Missing Equivalents\n\nLCSC part numbers are specific to the LCSC\u002FJLCPCB ecosystem. Use the `mfr` field (MPN) to cross-reference on DigiKey\u002FMouser.\n\nWhen an MPN has no exact LCSC match:\n1. Search by key parameters (e.g., \"100nF 0402 X7R 16V\")\n2. Look for pin-compatible alternatives from Chinese manufacturers\n3. Verify specs and footprint match — pad dimensions can vary even within the same package size\n4. As a last resort, mark as \"consigned\" and source separately\n\n## Tips\n\n- `is_basic` field matters — JLCPCB basic parts have no setup fee; extended parts cost $3 each\n- jlcsearch `stock` is JLCPCB assembly stock; the wmsc detail's `stockNumber` is LCSC's own stock — the two differ\n- MOQ and order multiples are no longer in the jlcsearch response — check the LCSC product page before ordering\n- Datasheet quality varies for Chinese manufacturers — cross-reference MPN on DigiKey for better docs\n",{"name":5,"description":7},"main","47790c5af225ba335e83c027413077333397539e","plugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc",474,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins","https:\u002F\u002Fhol.org\u002Fplugins\u002Fbest-codex-plugins","https:\u002F\u002Fgithub.com\u002Fhashgraph-online","https:\u002F\u002Fhol.org","Open-source standards and developer tools for interoperable AI agents: discovery, identity, communication, payments, privacy and security.","2026-11-11 14:40:14",{"source":8,"skillName":5,"commands":59,"prompt":69,"zipAvailable":70},[60,63,66],{"tool":61,"command":62},"npx","npx skills add hashgraph-online\u002Fawesome-codex-plugins --skill lcsc",{"tool":64,"command":65},"bunx","bunx skills add hashgraph-online\u002Fawesome-codex-plugins --skill lcsc",{"tool":67,"command":68},"pnpm","pnpm dlx skills add hashgraph-online\u002Fawesome-codex-plugins --skill lcsc","安装技能，技能地址：https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc\u002FSKILL.md",true,[72,78,82,86,90,94],{"path":73,"resourceType":74,"resourceTypeDesc":75,"sizeBytes":76,"sourceHtmlUrl":77},"scripts\u002F_core_path.py","SCRIPT","脚本",697,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc\u002Fscripts\u002F_core_path.py",{"path":79,"resourceType":74,"resourceTypeDesc":75,"sizeBytes":80,"sourceHtmlUrl":81},"scripts\u002Ffetch_datasheet_lcsc.py",6582,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc\u002Fscripts\u002Ffetch_datasheet_lcsc.py",{"path":83,"resourceType":74,"resourceTypeDesc":75,"sizeBytes":84,"sourceHtmlUrl":85},"scripts\u002Fprovider_lcsc.py",14518,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc\u002Fscripts\u002Fprovider_lcsc.py",{"path":87,"resourceType":74,"resourceTypeDesc":75,"sizeBytes":88,"sourceHtmlUrl":89},"scripts\u002Fsearch_lcsc.py",14516,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc\u002Fscripts\u002Fsearch_lcsc.py",{"path":91,"resourceType":74,"resourceTypeDesc":75,"sizeBytes":92,"sourceHtmlUrl":93},"scripts\u002Fsync_datasheets_lcsc.py",2640,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc\u002Fscripts\u002Fsync_datasheets_lcsc.py",{"path":95,"resourceType":74,"resourceTypeDesc":75,"sizeBytes":96,"sourceHtmlUrl":97},"scripts\u002Ftest_search_lcsc.py",20380,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002Faklofas\u002Fkicad-happy\u002Fskills\u002Flcsc\u002Fscripts\u002Ftest_search_lcsc.py",[99,107,114,121,146,170],{"skillNo":100,"name":101,"nameZh":6,"description":102,"descriptionZh":6,"repositoryFullName":8,"ownerLogin":9,"ownerAvatarUrl":10,"ownerAccountNo":11,"ownerDisplayName":12,"repositoryNo":13,"starsCount":14,"licenseSpdxId":15,"licenseFileUrl":6,"sourceHtmlUrl":103,"categories":104,"keywords":105,"publishedAt":106},"01M746ZWACVKMZ1BJXJZHYJSSX","migrate-to-e2e","Moves an existing Playwright, Cypress, Selenium, Appium, Detox, Maestro, or TesterArmy suite to e2e one slice at a time, with the old suite running beside the new one until each ported test is proven.
