name: adom-basic-parts-summary user-invocable: true description: Lead/core skill for the Adom Basic Parts — the 138 commodity passives and LEDs that Adom stocks on reels (79 resistors, 40 MLCCs, 11 LEDs, 6 inductors, 2 ferrite beads, across 0402/0603/0805). One-stop shop that answers: what the basic parts are, where each one lives on the Adom Wiki (per-MPN component pages with symbol + footprint + 3D + KiCad/Fusion downloads), how to query the live inventory, and which sub-skills cover deeper concerns (CAD fetching, parts search, board generation, Fusion library export). Use first whenever a question touches Adom's standard passive library — picking values for a design, building a Fusion or KiCad library from Adom's parts, checking CAD completeness, or any "what are the Adom basic parts and how do I find them". Trigger words — adom basic parts, basic parts, basic-parts-library, adom passives, adom resistors, adom capacitors, adom inductors, adom LEDs, adom ferrites, standard parts, commodity parts, build fusion library, basic-parts wiki, MPN library, in-house passives, what parts does adom stock, adom standard values, all_basic_parts board.

Adom Basic Parts

The 138 commodity passives + LEDs that Adom keeps on reels and loads into pick-and-place feeders. These are the standard building blocks for every Adom board. This skill is the hub — it tells you what they are, where to look them up, and which other skills handle deeper work.

Why this skill exists: Agents building a Fusion library from Adom's basics have wasted hours reverse-engineering where the parts live and have wrongly concluded "no passives are on the wiki" when in fact 128 of the 138 basic parts have full component pages (symbol + footprint + 3D + kicad_sym/kicad_mod/step/glb/lbr downloads). Load this skill first.

The 138 basic parts at a glance

is_basic = 1 in the inventory service. Everything else (is_basic = 0, the 35 "Other" parts — ICs, connectors, diodes, transistors, machine pins) is out of scope for this skill; for those see adom-inventory.

Ferrite Bead 2 0402 Murata BLM15*

Standard values (resistors): E24 from 0 Ω to 1 MΩ — 41 values in 0402, 38 in 0603 (0603 omits 0 Ω, 120 Ω, 2 kΩ, 5.6 kΩ). All 1% thick film, Royalohm primary.

Standard values (MLCCs): C0G dielectric for ≤ 220 pF, X7R for mid-range, X5R for ≥ 2.2 µF. 5% / 10% / 20% depending on value; reel qty 10 000.

LED colors: amber, blue, green, red, white in 0402 and 0603 (Inolux), plus WS2812B-2020 RGB.

Inductor values: 100 nH, 470 nH, 1 µH, 2.2 µH, 4.7 µH, 10 µH (Murata LQM18 ferrite core, ±5 % / ±20 %).

Ferrite values: 47 Ω, 600 Ω at 100 MHz (Murata BLM15, ±25 %).

Where to find every basic part

Three places, increasing depth:

  1. Inventory API (live stock, pricing, vendor cache) — see adom-inventory. Stats endpoint:

    curl -s https://inventory-2w8z8d9ojzzl.adom.cloud/api/inventory/stats
# { "parts_total": 173, "basic_parts": 138, ... }

  2. Wiki catalog page — https://wiki.adom.inc/library/basic-parts-library is a summary listing (HTML viewer with all 138 values, packages, MPNs, Mouser PNs, reel pricing). Carries no CAD itself — it's an index. View via:

    adom-wiki page get library/basic-parts-library

  3. Per-MPN wiki component pages — this is where the CAD lives. Each of the 128 matched basic parts has its own type=component page at https://wiki.adom.inc/component/<slug> that auto-renders symbol + footprint + 3D viewer and serves downloadable kicad_sym, kicad_mod, .step, .glb, and often .lbr (Fusion 360 / Eagle) assets.

Live recipe (when verifying or refreshing this skill)

# List every component page (paginate; default limit is 200)
for off in 0 200 400 600 800; do
  curl -s "https://wiki.adom.inc/api/v1/pages?type=component&limit=200&offset=$off"
done | jq -s 'map(.pages // .) | flatten | map(.slug)'

# Inspect a single basic part's full assets / samples / sub_skills
adom-wiki page get component/cr0402-fx-1002glf

# Slug convention: lowercase manufacturer PN
# e.g. CR0402-FX-1002GLF (10 kΩ 0402) → wiki slug cr0402-fx-1002glf
#      BLM15BA470SN1D (47 Ω ferrite)   → wiki slug blm15ba470sn1d
#      IN-S42ATA (amber 0402 LED)       → wiki slug in-s42ata
#      WS2812B-2020                      → wiki slug ws2812b-2020

Checking CAD completeness on a component page

The list endpoint does not expose has_symbol / has_footprint / has_3d_model at the top level — those are derived from the page's assets array. To tell a "full" basic-part page from a stub:

adom-wiki page get component/<slug> \
  | jq '.assets | map(.asset_type) | unique'
# A complete passive returns at minimum: ["kicad_mod","kicad_sym","step","glb","lbr","viewer_html",...]

Filter shortcut on the list endpoint:

curl -s "https://wiki.adom.inc/api/v1/pages?type=component&has_3d_model=1&limit=200"

Every basic part → wiki slug

The full snapshot, organised by type and package. URL pattern: https://wiki.adom.inc/component/<slug>. Rows marked ❌ no wiki page are the 10 parts that exist in the inventory but have no component page yet (see What's not on the wiki yet below for the consolidated list).

(All 8 Samsung CL21 0805 caps are missing — the 0805 row is the soft spot.) To fill any of these, use the chip-fetcher skill below.

Sub-skills (the deeper stuff)

Anything beyond "what are the basics and where do they live" is delegated. Use these in roughly this order depending on the task:

Live data & queries

  • adom-inventory — Query the live REST API at inventory-2w8z8d9ojzzl.adom.cloud. Stock, pricing with 30 % markup, BOM availability, vendor cache (Mouser/DigiKey/LCSC), order history. Includes smart lookup that understands color synonyms (yellow → amber) and package aliases (0603 = 1608). Use whenever the question is "do we have X / how many / what's our price / can we build this BOM."

Per-MPN CAD & wiki

  • adom-wiki-skillpack — CLI to read/write/search wiki pages, manage assets and sub-skills. The substrate this skill sits on top of.
  • chip-fetcher — Pulls manufacturer-grade CAD bundles (STEP + kicad_sym + kicad_mod + Altium .IntLib + Fusion .lbr + datasheet) for an MPN. Use to fill the 10 wiki gaps above, or grab CAD for parts that aren't basic.

Footprints & libraries

  • kicad-donut-pad — Generate KiCad annular-ring pads (for MEMS mic acoustic ports, NPTH copper rings, etc.).

Wiki skills you'll likely reach for

Not bundled as local Claude skills — read these on the wiki directly:

  • https://wiki.adom.inc/app/adom-symbol — KiCad symbol creator + viewer.
  • https://wiki.adom.inc/app/adom-footprint — KiCad footprint creator + layer HUD.
  • https://wiki.adom.inc/app/adom-lbr — One KiCad part → every major EDA tool. Exports a folder per tool: KiCad, Fusion 360 .lbr + 3D handoff, OrCAD EDIF, Altium .SchLib/.PcbLib. The right tool when an agent asks "build a Fusion library from Adom's basic parts" — feed each basic-part kicad_sym/kicad_mod/step triple through adom-lbr export.
  • https://wiki.adom.inc/skill/adom-sfconvert — Native Rust converter: EAGLE/Fusion .lbr + Altium .SchLib/.PcbLib → KiCad symbol + footprint.
  • https://wiki.adom.inc/app/adom-chipfit — Pair a .glb chip model with its .kicad_mod footprint, validate fit, bake a pin-1 dot.
  • https://wiki.adom.inc/skill/chip-sourcing-skillpack — Skill pack for sourcing chip CAD.

Building with the basic parts

The basic parts are the constituents of two ongoing initiatives. Reference (not re-execute):

  • All_Basic_Parts / All_Basic_PartsV2 KiCad boards — every basic-part value as a tiny test molecule in a 7×5 (or 13×N) grid, designed for sweeping characterisation. Layout params, KiCad-10 rotation convention, and generator-bug notes live in the local memory entry reference_combined-board-generation.md.
  • Component characterization wiki pages — interactive HTML per MPN with specs, impedance/derating charts, reflow profile, 3D viewer, schematic symbol, footprint, vendor pricing. Generators live at /home/adom/project/inductor-comparison/. Status as of 2026-06-03: 120 components published. See the project memory project_component-characterization.md.

Common agent tasks and which skill answers them

Task Where to start
"Build a Fusion 360 library of Adom's basic resistors" Use the Resistor — 0402/0603 tables above for the MPN→slug list, then the wiki adom-lbr app for the per-part export.
"Do we have 10 kΩ 0402 in stock and what does it cost?" adom-inventory → curl "$INV/api/inventory/check?mpn=CR0402-FX-1002GLF&qty=100"
"Where's the STEP file for the amber 0603 LED?" This skill → LED — 0603 table → in-s63bta → adom-wiki page get component/in-s63bta

Quick verification

The numbers in this skill are anchored to the live inventory. If something seems off:

# Confirm basic count
curl -s https://inventory-2w8z8d9ojzzl.adom.cloud/api/inventory/stats
# Confirm wiki-page coverage
curl -s 'https://wiki.adom.inc/api/v1/pages?type=component&limit=200' | jq '.pages | length'

If the per-type tables above appear stale (new basic parts added, or the 10 gaps closed), regenerate by pulling is_basic=1 from /parts, paginating ?type=component, and matching mfrPN.lower() to slug.
