Hi Sunkmail, Welcome to EasyEDA. There are a couple of ways to do this. You have to think about what your schematic is to represent. If it is simply to show how everything is to be connected then you can create symbols for the off board parts and just wire them in the schematic in the same way as all the other symbols. Then draw boxes round the relevant sections and add text to explain what is going on. However, if you want to create a schematic that is to be turned into a PCB then the schematic described above will not work because everything that is shown in the schematic will get pulled into the PCB design editor. A way round this is to create a project containing two schematic sheets. One for the PCB itself and one for all the off board parts. When you pass a design into PCB, you pass the entire contents of a Project into PCB design. You cannot select which schematic does or does not get passed into PCB design. Therefore, when you want to design the PCB, you create a new project and clone only the schematic sheet for the PCB into it. Then pass that schematic into PCB design. The "correct" way to do this is to draw a schematic for all the parts that are on the PCB and put that into one project. Then have a completely separate drawing - which can be a schematic but is more correctly a wiring diagram or, arguably, an assembly drawing but which must be in a separate Project - showing how the PCB is wired to all the off-board components.
