PDF schematic of the ASUS B250M-PLUS micro-ATX motherboard with the Intel B250 chipset, about 1.54 MB. No revision is given in the name. Use it to inspect the CPU VCore phases, DDR4 power, PCH supplies and the standby logic, and to locate the SPI flash when a BIOS reflash is planned. It is opened with any PDF reader, and text search speeds up following nets between pages. Verify the board revision printed on the PCB before trusting component values or the location of a given part.
