PDF schematic for the Gigabyte GA-H77N-WIFI motherboard, revision 1.1, compressed in a 772 KB RAR. This Mini-ITX board uses the Intel H77 chipset, as the model name indicates, and the drawings help trace VRM rails, standby power, clock and reset signals, and onboard wireless connections. Open the extracted file in any PDF reader. Gigabyte marks the revision on the PCB, usually near the slots, so verify it reads 1.1 before using these values for measurements.
