liontron-board-technical-library

CoWork skill for capturing Liontron mainboard technical data from en.liontron.cn — downloads specs, images, PDFs, and generates standardized markdown reference files.

CoWork Project: CW-014 — Liontron Board Technical Library Capture

Overview

This skill instructs CoWork to visit Liontron board product pages on en.liontron.cn, extract all technical information, download board images and PDFs, and produce standardized Markdown reference files for the MPM technical library. It uses Claude in Chrome to navigate and extract content, since the Liontron site renders its specification tables as images rather than HTML text. The skill was developed with the D-3588 RK3588 board as a reference and covers boards from all Liontron product series used by MPM (H, K, D, M, Fi, etc.). Output files follow a consistent naming convention and structure for direct use as KB source material.

Skills

Skill What It Does

liontron-board-technical-library Navigates to a specified Liontron board page, captures overview text and key features, identifies and downloads up to 5 technical images (main photo, overview, front I/O diagram, rear I/O, dimensions), downloads spec and mechanical PDFs, reads the spec table from screenshots, captures I/O port labels, and produces a standardized .md reference file. Trigger phrases: "process board [BOARDNAME] from the Liontron catalog", "capture Liontron board data", "download Liontron specs for [BOARD]", "get the technical reference for [BOARD]".

Setup Instructions

Install the skill by uploading liontron-board-technical-library-v1.0.skill via CoWork plugin settings
Ensure Claude in Chrome is connected and an active browser session is open
Verify CoWork can reach en.liontron.cn (no network restrictions)
To begin: "Process board [BOARDNAME] from the Liontron catalog"

Setup Checklist

Skill file installed in CoWork
Claude in Chrome connected
en.liontron.cn accessible from the browser session
Working folder available for downloaded files

Connection Details

Field	Value
Target site	http://en.liontron.cn
Browser tool	Claude in Chrome (`navigate`, `javascript_tool`, `get_page_text`)
Auth required	None (public site)
MCP server	None (skill-only, no server component)

Workflow Notes

Process one board at a time unless user explicitly requests batch mode
The spec table on each page is rendered as a large image — the skill scrolls to it and reads it from a screenshot; do not attempt DOM extraction for specs
All downloads use fetch+blob (not direct href) — direct downloads result in incomplete .crdownload files on this domain
Markdown files cannot be downloaded via blob URI on this domain; content is written to a new tab for copy-paste by the user
Images at offsetTop 0 with width exactly 1000px are thumbnail duplicates — skip them
Space image downloads at least 2000ms apart to avoid incomplete files
After each board, confirm with user before proceeding to the next

Completed Boards Log

Board	Date	Status
D-3588 RK3588	2026-03-19	Complete — reference board

Requirements

CoWork with Claude in Chrome connected
Active browser session open to any page (skill will navigate from there)
Network access to en.liontron.cn

Troubleshooting

Symptom	Fix
Downloads result in `.crdownload` files	Use fetch+blob method, not direct anchor href
Spec table extraction returns no data	Table is image-based — scroll to offsetTop ~11000-13000 and read from screenshot
MD file download fails	Write to new tab via `document.open/write`, instruct user to copy-paste
Wrong images downloaded	Use offsetTop + naturalWidth/naturalHeight to identify correct technical images; skip 1000px-wide thumbnails
Page content missing after navigation	Wait 2 seconds after navigation before running JavaScript extraction
