Finished the PCB!! 100% of the DRC errors are fixed.
I also added a panel with all the back capacitors so I can get single sided asembly, and then I will hand solder all the capacitors

FINISHED ROUTING GND!! I also fixed the DRC... That was a pain...
I had over 1k Errors (Still got a lot of warnings, but they're related to silkscreen overlap), luckily a big part of them were due to bad configuration of constraints and net classes.

Half of the GND routing is done!...
This is taking, like, forever. There are 1024 LEDs, 512 remaining ...

I finished routing most of the +5V! It took a while.
Now time to do the GNDs :sob:

Update attachment

Instead of using SMD connectors, I'll just use solder pads and manually solder wires for the power, I also placed all the capacitors

It should now be good, but prob still have some I have missed

Wow, that took a while. My hand hurts, 😭.
Hope I haven't wired them wrong or missed any.

nvm, I missed a big zone

For this LED Display, I went with WS2812B LEDs, as they would be easier to route. https://www.lcsc.com/product-detail/C5349953.html
For this PCB I will go with a 32x32 matrix, with a total of 1024 LEDs, cheap enough so I can afford it.
My initial idea was to use 32 channels to have as little input latency as possible, but I found out it wasn't feasible, so I ended up with only 16. This should still be fast-enough.
I'd like to have a way to drive the display via I2C, SPI or some sort of easy to use protocol from an external MCU.
