Gigabyte GA-B85M-D3V desktop motherboard schematic in PDF, compressed as RAR, for revision R20 as the name suggests. The board uses the Intel B85 chipset in micro-ATX form. A technician uses these drawings to follow VRM and standby rails, check the power-on sequence, find the SIO and BIOS chip circuits and track down shorted parts. Gigabyte released several PCB revisions of this model, so compare the revision printed near the PCIe slots or board edge with this document before measuring against it.
