Gigabyte GA-A320M-S2H boardview for revision 1.0, compressed into a ZIP of about 702 KB. The A320 board targets AMD socket AM4 processors, and the layout file helps during diagnosis by showing component positions, part designators and net connections across the PCB. Technicians use it to find where a rail is generated, locate a shorted capacitor or follow a signal from the socket to the chipset. Open the extracted file in a boardview viewer and make sure the PCB revision agrees with 1.0.
