Curated by Skill Harbor: the production sourcing skill in the KiCad collection. LCSC is JLCPCB's sister company, so the two share the same parts library and the same C-number part numbers, which makes LCSC the natural source when a board will be assembled by JLCPCB. It finds components by LCSC number or manufacturer part number, checks stock and pricing, downloads datasheets, analyzes specifications, and syncs a local datasheets directory for a KiCad project, with batch part-number list seeding for bulk work without a project. It also covers cross-referencing and finding equivalents when a part is missing, and the differences from DigiKey and Mouser, which the collection positions for prototypes instead. By @aklofas, listed here with credit to its creator. Honest caveats: the community search API used by default needs no API key, but the official LCSC API requires approval, so do not assume official API access; a website fallback exists but is less reliable; and production quantities deserve the same price and stock recheck as prototypes before ordering. Skill Harbor never reviews the code, review it yourself before use.
Version:
Quick answer
LCSC Parts Search is a free Muse skill that finds LCSC components by LCSC number or part number, checks stock and pricing, downloads datasheets and syncs a directory, with seeding and equivalents. Sharing the JLCPCB library and C-numbers, it is the source for JLCPCB assembly. Community API needs no key, official API requires approval, prices need a recheck before ordering.
Install
Copy the install package below, then paste it into MusePrerequisites: an AI agent with file tools (Read, Write, Bash), such as Claude Code or Codex; Python 3 for the helper scripts. No API key is needed for the default community search API; official LCSC API access requires LCSC approval and is optional. Install "LCSC Parts Search" for me. A skill that searches LCSC Electronics by LCSC number or manufacturer part number, checks stock and pricing, downloads datasheets, and syncs a local datasheets directory for a KiCad project, with JLCPCB assembly compatibility. Repository: https://github.com/aklofas/kicad-happy/tree/main/skills/lcsc 1. Fetch the SKILL.md file (plus its scripts/ folder) from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). It must never contain hardcoded secrets. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "lcsc". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. search by C-number for JLCPCB assembly parts). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it is in the prerequisites above. Rules: do not touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.

Questions
How do I install a skill?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the skill up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a skill before installing it.
