Quanta R53 AMD Comal UMA^Muxless REV 1A

Second copy of the Quanta R53 schematic for the AMD Comal platform, marked UMA and muxless, revision 1A, in a 954 KB PDF. Muxless means the optional discrete GPU sends its frames through the integrated graphics instead of a display switch, so both graphics paths appear in the drawing. Quanta designed this as an ODM board for other brands. Technicians use it to measure the APU and graphics supply rails, trace signals and locate test points or shorted parts. View it in a PDF reader and confirm the PCB marking matches R53 rev 1A first.
