EDA stands for Electronic Design Automation its an umbrella term for Software like KiCad, EAGLE, Altium, Easyeda and more.
You exported just the Gerber files, Gerber does not include information about the connections between components, the list of components you used and if the components are surface mounted or trough hole. You can think of gerber files like a painting of your mechanical layers.
Because the export and preperation of this data can be quite complex we support the direct upload of the pcb file from various software packages. We will use the pcb file to export the data we need using our software pipeline.
At the moment this is unfortunately not possible for Easyeda.
You can find a list of the supported design tools here:
