Schematic PDF packed in a rar archive for a board labelled P51 MB NPB, version B; the name gives no manufacturer or full model name, so identification relies on the board itself. A circuit diagram of this kind is used to trace power rails, follow enable signals, check the charging stage and read connector pinouts. Open it in any PDF viewer. Before relying on values, compare the board name and version marked on the PCB with this document, because revision changes can alter components.
