As I said, I didn’t see the dimensions of the full PCB for the 2.8 inch version, and because of that, I was going to need to change the board (since I don’t want to increase the size of the final product). So I went after the dimensions of the 2.4 inch version and made the rectangle just to represent the space it would take up in the PCB schematic.
A strange thing is that when I went to change the 3D model of the device, instead of changing it, it added another part to it. I had to overlap them so it wouldn’t look so weird there in EasyEDA.
