Boardview file for the Samsung N7100, the Galaxy Note II model code, in .pcb format at 20.2 MB. A boardview shows the physical position of every component and lets you click a pin to highlight its net, which makes finding test points and shorted capacitors much faster than reading schematics alone. Files with the .pcb extension can come from different layout tools, so try a multi-format viewer such as OpenBoardView-compatible or commercial boardview software. Confirm the board matches the N7100 before relying on it.
