ALWAYS CREATE GROUND PLANE
ALWAYS CREATE GROUND PLANE
Having a common ground on your PCB is imperative as it gives all of your traces the same reference point for measuring voltage.
If you use traces to route to ground instead of using a ground plane, you’ll find yourself with a multitude of different ground connections on your board, all with their own resistance values and voltage drops,
To avoid all of this , we always recommend creating a dedicated ground plane on your PCB layout.
