Hello, I am pretty new to laying out PCB's. I am laying out a board that will be populated by a NodeMCU some logic level switchers, and some screw terminals but it would be nice if I could have power on-board too. Would it be in bad practice to have a 2 layer board (2oz copper) with one layer as a GND plane and the other layer as a 5v plane? IF this is acceptable, how could I calculate the max current of the board? I'd like it to be able to handle 60a @ 5v. The copper pour areas are 58.4mm x 54.6mm with data traces running through them. I'm not opposed to making the board larger to accommodate, but I don't know how to figure it for a whole plane, only trace width. This would obviously rule out any via stitching. The end goal is to convert the 3.3v logic to 5v logic for some "Neopixel" strips, the reason I can't just use the 3.3v is because it will be going through a run of 18g wire and the voltage drop is too great. I would also like to be able to power them from the same terminals (power will have to be injected along the way for some of the runs, but that's a whole separate ordeal).
