Wiring Diagram Review Request for 1156 LED matrix

I’m getting down to the nitty gritty on a large LED project, and would be so grateful if I could get the critical eye of more experienced LED folk before I roll up the sleeves on wiring.

The basics: 34x34 matrix, with 3 outstanding questions:

  • Do I need to account for data lag via serpentine dataline by using multiple segments?

  • Do I need larger wire for my wires leaving the power supply?

  • I’m not sure what type/power fuses to use on my power lines. (I’ll put the top fuse in the diagram on the other side of the board, that was a graphical error)

Attached is my schematic with specifics. Apologies for it being atypical; just whipped it up in Illustrator. I don’t think I’ve left out any critical info but please let me know if so!


Thanks for reading!

You won’t get much speed with one data line and 1,156 LEDs. Best performance is about 500 per pin, but consider what you will be doing with it.
