This is a 2 layer board I designed in Altium Designer. I wanted to see if any expert PCB designers can leave some feedback or advice for my PCB.
My PCB is a slot machine powered by an Arduino Nano. The displays are not going to be soldered directly to the board so I can change it if any of the displays break.
I know there are many vias in the board, but I figured since I only have two layers I would have the power and signal traces on the top layer and the ground plane on the bottom layer. When I would require a jump I would create the smallest jump on the bottom layer to keep the power and signal on the top layer. This method might not makes sense on such a simple board like this or would it make more sense to route the signal on the bottom as well to get rid of the vias.
