PDF schematic document for the Samsung SM-G130E, with no other details in the name beyond the model code. It can serve to trace power and charging circuits, check signal paths between the processor and peripherals and locate components by their references during board-level repair. Open it with any PDF reader and search for designators to move between pages. Check the model code printed on the device, since similarly numbered Samsung variants can use different hardware and the pages may not match.
