JLCPCB Parts Library

Know it's in the JLCPCB library — Basic or Extended — before you commit a board to fab.

adom-jlcpcb is the single-vendor JLCPCB / LCSC tool for the Adom ecosystem — one Rust binary, three faces:

• CLI — adom-jlcpcb search | part | health for quick JSON-returning shell use and BOMs.
• Hydrogen app — adom-jlcpcb app opens a searchable UI as a first-class Hydrogen tab.
• Backend service — adom-jlcpcb serve runs the shared proxy (port 8779) that powers the service-jlcpcb container and feeds adom-parts-search.

adom-wiki pkg install adom-jlcpcb
adom-jlcpcb search "0402 10k resistor"

Basic vs Extended — the question that costs money

On a JLCPCB assembly run, Basic parts are pre-loaded on the line (no fee), while Extended parts add a per-part feeder setup charge. Picking a Basic equivalent up front can shave real money off a build. adom-jlcpcb shows the library tier on every card, alongside LCSC code, stock and price, so you design around what's actually cheap to place.

Catch the Extended part before fab does

Search your MCU or regulator and you'll see at a glance whether your first pick is Basic, and what the Basic alternative is. Here a popular STM32 is Basic, while a drop-in GD32 equivalent is Extended — exactly the trade-off you want to make before the board goes out.

Scriptable from the first keystroke

search returns JSON; part fetches one LCSC code; health checks the backend. Pipe it into jq, a BOM, or a board-cost estimator.

How it works

  any container                          service-jlcpcb
  $ adom-jlcpcb search "LM358"  ──POST──▶  adom-jlcpcb serve  (:8779)
  $ adom-jlcpcb app                        LCSC resolve + cache
    (Hydrogen webview tab)
                                                 │
                                                 ▼
                                          JLCPCB / LCSC parts API

JLCPCB is an assembly-first workflow, so in adom-parts-search it shows as a library column rather than competing on the buy-now recommendation — but for "can JLCPCB place this for me, and is it Basic?" it's the fastest answer in the workspace.

Open source — make it yours, then give it back

This app is open source under the MIT license. Fork it, rewrite it, rename it, bend it to your own workflow — and when you've made it better, send your changes back to the Adom Wiki so the whole community benefits. Every wiki page is a git repo with a package registry on top, so contributing back is first-class — improvements that land here ship to every Adom user who installs the app.

adom-wiki pkg install adom-jlcpcb      # install it
#   …edit the source to taste…
adom-wiki pkg publish             # publish your own fork, or
#   open a pull request against this page so the change lands for everyone

One caveat — the search backend is an Adom service. The actual lookups run against Adom's hosted JLCPCB / LCSC backend (service-jlcpcb), which uses Adom's vendor API credentials and counts against Adom's quota. That hosted backend is an Adom service and is subject to change — rate limits, endpoints, and availability can move at any time. Everything client-side (the CLI, the webview, the rendering and recommendation logic) is yours to fork and republish; the cloud API quota is not.
