Schematic in PDF format for the Gigabyte GA-P55A-UD3P motherboard, revision 2.0, compressed in a 1.59 MB RAR archive. For a P55 desktop board it lets a technician follow CPU VRM phases, standby and memory rails, the power-on sequence and SuperIO signals. It is handy for locating the source of a short, checking MOSFET drivers or identifying the BIOS chips. Confirm the PCB is marked revision 2.0 before measuring against it, since earlier revisions may differ in parts and nets.
