I am an engineering student at Oak Ridge High and have started to learn PCB design. I just finished designing my first PCB and had several concerns about it. My main concern is that I'm not sure is the supply rails for the 5V and GND are large enough. I'm expecting at most peaks of around 15-16 amps to go through this board.
If anyone would be able to take a look at my board design before I have it made and then possibly fail that would be so helpful. Any suggestions on changes are readily welcome. This board is going to be used to drive a 8x8x8 cube of LEDs.
The board and schematic files are in the enclosed link: https://www.dropbox.com/sh/33xup0rf5dw9f36/AABldcXm4Cta2-585d3HQwXLa?dl=0
