    Hi guys. I'm using the L298n H bridge to drive some motors. Assuming I use a 50mil trace width on my power and ground lines (given to me by a calculator), where do I STOP making the widths this large? In other words, do I make all the ground lines on my PCB thick? Or should I just make a thick one from the H bridge to the DC jack port and leave all the others thin?

    Thanks guys
