Schematic for the ASUS NR2201ZE board, revision 2.1, as a large 18.2 MB PDF. The name names only the project code and not the retail model, so match it to the board marking. Technicians use these diagrams to trace power rails, check the power-on sequence, find pull-ups on enable lines and work out where a short originates. A boardview exists under the same code with a different revision, so note any differences between versions. Any PDF reader opens it, and searching by net name speeds up work.
