Hi You can check the DRC error at  and then you need to copper pour[https://docs.easyeda.com/en/PCB/Copper-Pour/index.html](https://docs.easyeda.com/en/PCB/Copper-Pour/index.html)

Thank you for your answer, I corrected the problems. But what I would like to know is if my pcb could work according this picture (which I realized and which works in real)

Here are some steps to follow: 1) Read (1) and (2.2) in: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f) 2) Check that the Schematic that you have drawn in EasyEDA is connected correctly to the Fritzing diagram. 3) Check that you have created the schematic correctly in terms of the necessary assignment PCB Footprints  to the Schematic Symbols and that you have added the required BoM information. 4) Read and go through the check list of (4) in: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f) 5) Then and only then, Convert the Schematic to PCB. 6) Layout and route the PCB. 7) Read and go through the check list of (6) in: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f)
