PCB Routing Assistance


Processing was stopped.
Here's a summary of what I was working on:
Planning PCB layout
I'm considering moving the layout inside and cleaning up any traces. I could use the placement tool to preserve the board while deleting dangling traces. The user asked for an 8x8 matrix, though I currently have four 4x4 modules arranged in a 2x2 grid, plus the MAX chip on the far right. The board is quite large at 120x100, so I shouldn't resize it. I need to compact the matrix in the center with the controller nearby and update my to-do list.
why the file tab is empty?
I’ll check the project files/assets state so I can tell you whether the Files tab is genuinely empty or if this is a view/sync issue.
The Files tab is empty because this project currently has 0 project documents saved there. There is only one asset in the project, a .glb file named liquid-diffuser-acrylic.glb, and it is not marked as a thumbnail, footprint, 3D model, or board shape.
So nothing was deleted by the recent routing attempts — there just aren’t any markdown/spec/report files in the Files tab right now.
make something related to project inside the files tab
I’ll create a concise project-related file in the Files tab summarizing the 8x8 MAX7219 LED matrix module, current layout intent, and known routing cleanup items.
Created a project file in the Files tab: 8x8 LED Matrix Module Notes.
It summarizes the MAX7219 8x8 matrix architecture, intended PCB layout, routing cleanup plan, and basic bring-up checks.
