name: electronics-bom description: | Electronics BOM and robot-dog component selection MVP. Use this skill when the user asks for electronic BOM, MCU/driver/encoder/power/connector selection, JLCPCB/LCSC-ready part candidates, curated robot electronics library, BOM rationale, availability checks, or component choices to feed pcb, circuit simulation, firmware, and digital-twin gates. owner: hardware status: active phase: P1-mvp since: 2026-06-02 updated: 2026-06-08

This skill selects early robot-dog electronics BOM candidates from an offline curated catalog and writes machine-readable BOM artifacts. The MVP is a stable file contract for pcb, circuit-simulation, firmware, and robot-dog-digital-twin; it does not perform live purchasing or guarantee current stock/pricing.

When To Use

Use this skill for:

MCU, motor driver, encoder, IMU, regulator, battery connector, and protection part candidates.
Producing a BOM contract before PCB layout.
Selecting JLCPCB/LCSC-friendly common parts from an offline library.
Writing electronics_bom.json and selection rationale for downstream skills.

Workflow

Read <project>/bom_request.yaml.
Match requested categories against the curated catalog.
Score candidates by fit, voltage/current margin, package preference, assembly tier, and stock status.
Write reports into <project>/reports/ and selected parts into <project>/electrical/library/.

Commands

python skills/electronics-bom/scripts/select_parts.py skills/electronics-bom/examples/quadruped_mvp
python skills/electronics-bom/scripts/check_availability.py skills/electronics-bom/examples/quadruped_mvp

Rules

Treat unavailable required categories as blockers.
Prefer jlcpcb_basic over jlcpcb_extended when scores are otherwise close.
Do not claim live prices or stock unless a live connector is explicitly added and run.
Do not place orders. Query/selection is not a transaction.
Do not import sibling subskill code. Read files only.
