USB

 

So: for current to flow in a circuit, it has to flow from someplace and to someplace. In the case of this USB signal, it needs to flow back to ground. I used a ground pour on both sides to try to accomplish that. Unfortunately with only two layers, they're not very contiguous. 3/ pic.twitter.com/4sNOKy28Rn
