Quanta schematic in PDF form for the UM2 project, UMA graphics variant, mainboard DAUM2BMB8C0, labelled UM2B, in a 611 KB RAR archive. DA-prefixed board numbers follow the Quanta scheme, and the project letters in the middle match the UM2 code. UMA means the board uses integrated graphics without a dedicated GPU. The diagram helps trace power rails, follow signals between connectors and find faulty parts. Make sure the PCB carries the same board number, since discrete-graphics versions of a project differ in layout.
