How to better stitch the ground plane ? #18

Closed jalinei closed 2 years ago

I do have a concern regarding the bottom tracks that kind of break your ground plane apart. I understand the routing constraints here, as it is a 2 layer PCB, but you should consider adding more via stitching from top to bottom to permit return currents to cross this ground plane discontinuity.

Board is now 4-layer with two inner layers being GND. There should not be any issue with interrupted GND plane anymore.
