## Per-Board Processing Instructions
For EACH board the user asks you to process, follow ALL steps below in order.
Replace [BOARDNAME] with the board model (e.g. "D-3568", "K4", "H-3568").
Replace [CHIPSET] with the chipset name (e.g. "RK3568", "RK3399").
---
### STEP 1 — Navigate to the Board Page
Navigate to the board's URL from the catalog above.
Wait for the page to fully load before proceeding.
---
### STEP 2 — Capture the Board Overview Text
Use document.body.innerText or read_page to extract:
- Board name and subtitle (e.g. "D-3588 Motherboard / Edge Smart Motherboard")
- Full overview/description paragraph
- All bullet point key features (lines starting with "●")
Note: The Liontron site renders most content as images inside a single-page layout.
The overview text and bullet points near the top of the page are the main extractable text.
---
### STEP 3 — Identify and Record All PDF Links
Use this JavaScript to find all PDF links on the page:
Array.from(document.querySelectorAll('a[href$=".pdf"]'))
.map(a => ({ text: a.innerText.trim(), href: a.href }))
Typically there will be two PDFs:
- Specifications (labeled "Specifications" or "SPEC")
- Mechanical Drawings (labeled "Mechanical Drawings" or "MECH")
Record the full URL of each PDF found.
---
### STEP 4 — Identify All Board Images
Use this JavaScript to find all product images:
Array.from(document.querySelectorAll('img'))
.filter(img => img.src.includes('/Products/'))
.map((img, i) => ({
index: i,
src: img.src,
w: img.naturalWidth,
h: img.naturalHeight,
offsetTop: img.offsetTop
}))
IMPORTANT — Image Identification Guide:
The page contains many images. Use offsetTop position and image dimensions to identify:
- Index 0 (offsetTop ~0, ~800x800): Main board product photo — name: [BOARDNAME]-Board-Main-Photo.jpg
- Index 1 (offsetTop ~330): Board overview/feature photo — name: [BOARDNAME]-Board-Overview.jpg
- Large image at offsetTop ~8000-9000 (tall, ~1920x2000+): Front I/O labeled diagram — name: [BOARDNAME]-Front-IO-Labeled-Diagram.jpg
- Large image immediately after (~1920x2000-3000): Rear I/O view with Micro-SIM — name: [BOARDNAME]-Rear-IO-MicroSIM.jpg
- Large image after that (~1920x1500): Board dimension diagram (shows 135mm x 95mm) — name: [BOARDNAME]-Board-Dimensions.jpg
DO NOT download images at offsetTop 0 with width exactly 1000px — these are thumbnail
duplicates of the larger originals and should be skipped.
---
### STEP 5 — Download Images via fetch+blob
For each identified image, use fetch+blob to ensure a complete download (do NOT use
direct anchor href download — it results in incomplete files on this domain):
fetch(imageUrl)
.then(r => r.blob())
.then(blob => {
const url = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
a.download = 'FILENAME.jpg';
document.body.appendChild(a);
a.click();
setTimeout(() => { document.body.removeChild(a); URL.revokeObjectURL(url); }, 1000);
});
Space downloads at least 2000ms apart (use setTimeout with idx * 2000 delay).
Download a maximum of 5 images per board:
1. Main board photo
2. Board overview photo
3. Front I/O labeled diagram
4. Rear I/O view
5. Board dimension diagram
---
### STEP 6 — Download PDF Files via fetch+blob
Use the same fetch+blob method for PDFs. Name them:
- [BOARDNAME]-[CHIPSET]-Specifications.pdf
- [BOARDNAME]-[CHIPSET]-Mechanical-Drawings.pdf
Example:
fetch('http://en.liontron.cn/d/file/Products/..../filename.pdf')
.then(r => r.blob())
.then(blob => {
const url = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
a.download = 'D-3568-RK3568-Specifications.pdf';
document.body.appendChild(a);
a.click();
setTimeout(() => { document.body.removeChild(a); URL.revokeObjectURL(url); }, 1000);
});
---
### STEP 7 — Scroll and Capture the Full Spec Table
The detailed specification table is NOT in the DOM as readable text. It is rendered
as part of a large image on the page. To capture spec data:
1. Scroll down to approximately offsetTop 11000-13000 (where the spec table appears)
2. Take a screenshot at each scroll position to capture the full table
3. Read the spec values from the screenshot visually
The table will contain these sections (read each from the screenshot):
- System: CPU, GPU, NPU, RAM, ROM
- Display: LVDS, HDMI, MIPI, eDP
- Audio: Headphone/MIC, Line Output, MIC Input, Amplifier Output
- I/O: USB Host, USB OTG, TF Card, Serial Ports, SATA, RTC, I2C, Backlight, GPIO,
Infrared, Button, Pilot Lamp, Camera, CAN Bus, POE, HDMI Input
- Network Connection: Ethernet, WiFi, Bluetooth, 4G/3G
- Power: DC Input
- Mechanical Structure: Size, Thickness, Structure Compatible
- Environment: Operating Temperature, Humidity
- Operating System: Android, Linux
---
### STEP 8 — Capture I/O Port Labels from Diagram
Scroll to the "Rich I/O, Easy to Expand" section (approximately offsetTop 8000).
Take a screenshot of the labeled board diagram (Front I/O).
Read all port labels from the diagram and record them grouped by board edge:
- Top Edge labels
- Right Side labels
- Bottom Edge labels
- Left Side labels
- On-Board labels
Then scroll further to capture the Rear I/O diagram and note the Micro-SIM label.
---
### STEP 9 — Compose the Markdown File
Using all captured data, write a Markdown file following EXACTLY this structure
and section order. Open a new tab, write the content using document.open/write,
then instruct the user to copy the text and paste into their Markdown editor.
File naming convention: [BOARDNAME]-[CHIPSET]-Liontron-Technical-Reference.md
Example: D-3568-RK3568-Liontron-Technical-Reference.md

## CoWork Skill Integration Notes
Skill Category: Hardware / Display Systems / Embedded Boards
Primary Use Case: [describe board's primary application]
Key Search Terms: [chipset], [boardname], Liontron, [series], embedded, AIoT
Board Family: [series] (note any compatible structures)
Typical Applications: [list from page content]
```
---
### STEP 10 — Deliver to User
After completing all steps for a board:
1. Confirm all downloads completed (images + PDFs)
2. Present the full MD file content in a new tab titled [BOARDNAME]-[CHIPSET]-Liontron-Technical-Reference.md
3. Instruct the user to select all text (Cmd+A), copy (Cmd+C), and paste into their Markdown editor
4. Ask if they are ready to proceed to the next board
---
## Processing Order and User Interaction
- Process one board at a time unless the user explicitly requests batch processing
- After completing each board, confirm with the user before starting the next
- Keep track of which boards have been completed
- If a board page has no PDF links, note "No PDF available" in the documentation section
- If a board page has a different layout or missing sections, note what was unavailable
---
## Known Site Behaviors and Gotchas
1. SPEC TABLE IS IMAGES: The detailed specification table on each page is rendered
as a large image, not HTML text. You must scroll to it and read it visually from
a screenshot. Do not expect to extract it from document.body.innerText.
2. BLOB DOWNLOADS REQUIRED: Direct anchor href downloads from this domain result in
incomplete .crdownload files. Always use fetch+blob approach for all downloads.
3. MD FILE DELIVERY: Chrome blocks data: URI and blob: URI downloads of text files
on this domain, resulting in .crdownload. Instead, write content to a new tab
using document.open/write and instruct user to copy-paste into their MD editor.
4. IMAGE INDEX MAPPING: The page contains 20+ images including marketing graphics
with blue/dark backgrounds. These are NOT the technical diagrams. The correct
technical images are identified by their offsetTop position (see Step 4).
Images with offsetTop of 0 and width of 1000px are thumbnail duplicates — skip them.
5. PAGE LOAD: The page loads fully on navigation. No lazy loading issues observed,
but allow 2 seconds after navigation before starting JavaScript extraction.
6. PDF LINKS: PDF links are present in the page as standard anchor tags with href
ending in .pdf. They are visible as "Specifications" and "Mechanical Drawings"
buttons near the top of the page, just below the header banner.
