Schematic in PDF format for the ECS H61MXL-K motherboard, about 1.13 MB. The model name points to an Intel H61 chipset micro-ATX platform, though no revision is given in the file name. The diagram is useful for tracing standby and CPU core power circuits, checking the Super I/O and BIOS chip connections, and following signals from the chipset to ports. Compare the board revision printed on the PCB with the revision shown on the schematic pages before relying on component values or net names.
