Samsung Galaxy A50 schematic, model SM-A505F, supplied as a 7.32 MB PDF. The diagram is the reference for working through no-power, no-charge, no-display and network…

PDF reference for the CD4050, the CMOS hex non-inverting buffer, at 67.1 KB. Although classed as a schematic, it is probably a compact datasheet with pinout and…

Datasheet PDF for the 2SA2062 transistor, 29.9 KB, the same size as the neighbouring 2SA2063 file, which hints at a shared document layout.

Compal schematic for board LA-4105P used in an HP laptop, a 1.48 MB PDF. The name gives no exact HP model, so identify the board by the number printed on the PCB.

A 359 KB PDF named for the 2SC2498, a transistor designated under the JIS scheme, where 2SC identifies NPN devices.

The 2N6794 PDF, around 129 KB, sits in the schematic section but its name holds only a JEDEC semiconductor number. No host equipment, revision or board code is stated.

Schematic package for the Huawei P8 smartphone, compressed into a 6.70 MB RAR archive. No board number or hardware revision appears in the name, so the specific PCB…

CD4017 document in PDF form, 81.0 KB, for the CMOS decade counter with ten decoded outputs.

Part number 2SA1533 names this 51.3 KB PDF, with an unexplained _E suffix; despite the schematic category it is presumably the transistor datasheet.

Schematic set for the Huawei Y7 Prime 2019 smartphone. These diagrams show power management, charging, battery, display and RF circuit blocks, with component references.
