Schematic and block diagram set for the Xiaomi Redmi Note 4, catalogued as firmware but described by its name as circuit documentation. The block diagram gives an overview of how the processor, PMIC, memory and peripherals connect, while the schematic pages show detailed nets for tracing power rails, charging and display lines. Technicians use it to locate shorts and check supply voltages on a dead phone. The Redmi Note 4 exists in MediaTek and Snapdragon versions, so confirm your board matches the drawings.
