Contribute data via CRT

Dennis edited this page Aug 27, 2026 · 4 revisions

Go to Wiki Home.

Spotted a wrong value, a missing part number, or do you have a datasheet, photo or scope reading that others would benefit from? You can suggest it directly from the Contribute tab - no GitHub account, no spreadsheets, no technical knowledge needed.

Your suggestion is sent to the developer for review. Nothing on your own machine is changed, and nothing goes live until it has been checked. Once it is approved by application developer (maintainer of the online source data), it reaches everyone automatically the next time the application updates its data.

1. Pick your board

At the top of the main window, select the hardware and the board revision you want to improve. The "Contribute" tab always shows the board that is currently selected.

2. Open the "Contribute" tab

You will see all the components of the board, grouped in columns by category (ICs, capacitors, resistors and so on). Hover a label to see its full name.

The line "Board Excel data last revisioned" tells you how fresh the current data is.

3. Click the component you want to change

Click a board label (for example U1 or C15) and the Component contribution editor opens in full screen. Everything in it is already filled in with the data the app has today — you are simply correcting or extending it.

4. Make your changes

The editor is divided into collapsible sections. Click a heading to open it. The number in brackets tells you how many entries it already holds.

Section What belongs here
Component The basics: friendly name, technical name or value, part number, category, short description
Component images Photos and oscilloscope readings for this component, with the scope settings used
Component local files Files about this component — datasheets, instructions, manuals
Component links Web links about this component
Board local files Files covering the whole board — service and troubleshooting manuals
Board links Web links about the whole board — repair logs, YouTube videos

Then:

  • To change something — just type in the box. Correct a wrong value, fill in a blank one.
  • To add something — click the Add new … button at the top of the section. A blank row appears; fill it in.
  • To delete something — click the Remove button on that row.

Attaching a file or an image

In any row that has a File box, click the box and a normal file browser opens. Pick the file from anywhere on your computer — a photo, a datasheet, a screenshot. The file name appears in the box, images show a small preview, and the file itself is sent along with your suggestion.

The File location dropdown next to it says which folder the file should end up in. Leave it as it is unless you have a reason to change it.

Can't find your component in the list? Pick the closest one and simply explain in the comment (next step) what should be added. The developer takes it from there.

5. Write the mandatory comment

At the bottom, describe what you changed, what was wrong or missing, and anything the developer should double-check. Please also mention which exact board revision you have — boards vary, and that detail matters.

This box cannot be left empty.

6. Enter your email and send

Type your email address in the field at the bottom left. It is required, so the developer can come back to you with questions, and it is remembered for next time.

Click Send contribution update. A progress message appears while it is sent, and you are told when it has arrived:

Contribution submitted successfully - thank you :-)

If something goes wrong, the message says so and you can simply try again.

Use Cancel to close the editor and throw your edits away. The and buttons jump to the top and bottom of a long form.

Worth knowing

Do note that the edits you do will not be used here-and-now in your own setup - it is meant as a suggestion for the developer to consider your data edit, and if this is then approved, then it will be incorporated to the online data source, and then it will be available from there. This is normally a pretty fast process... at least within a week or so 😁

That's it

Thank you — every correction makes the data better for the next person repairing the same board.
