I assigned the footprints to the schematic components. Then i converted in into pcb. However i am facing the problem that the 13th pin of the xiao board is also being assigned as 5v . The same problem is happening in the oled module. I thought that i had downloaded the wrong footprint for the board. but then i downloaded from the official site and uploaded them but still facing the same problem. Later i checked the problem was i had done a huge blundr. All the things are correct just at one place i had mistakenly connected the gnd and 5v. (spent too much time but learned something ). Will now work on designing the pcb and the orientation of components. Pls let me know if you have any suggestions for the same.
