The vias shall be round and have a diameter of 2.5 mm and a drill of 0.5 mm. |

| + | • Traces shall have a width of at least 0.8 mm. If yours is smaller you can use the ’change’ tool to set a bigger width. | ||
| + | |||
| + | • If a connection is made the yellow line should disappear. If it persists you have to look for the error. | ||
| + | |||
| + | for a better and easier connection let’s define a ground plane on the bottom layer and top layer. use the ’polygon’ tool to make a rectangle around the dimension of your board. | ||
