Spanish-language electronics series El mundo de la electronica, issue 18, around 1010 KB as a PDF.

Documentation for the 2SC4781 in a 120 KB PDF, indexed as a schematic though the name matches a discrete semiconductor part.

An 87.9 KB PDF for the 2SA1509 transistor, listed under schematics but named as a single component. JIS numbering identifies 2SA parts as PNP transistors.

Schematic for the Asus-branded ADP-90SB BB laptop adapter, compressed into a 270 KB rar.

Nokia N95 schematic package, numbered as part 3 of a series, packed as a RAR archive of roughly 20 MB.

Spanish multimeter table in PDF form, 171 KB, apparently a quick reference chart rather than a schematic for any device.

Full PDF schematic for Lenovo board NM-D461, revision 0.1, 3.08 MB. NM-xxxx numbers come from LCFC, the ODM that builds Lenovo laptop boards.

Second schematic copy for the Toshiba Tecra A11, carrying the same FHNSY1, DPL99060G01 and A5A002688010 identifiers, at a slightly larger 1.86 MB in PDF format.

Samsung Galaxy Z Fold 4, model SM-F936B, full schematic in PDF form at 27.4 MB. Foldables have several boards and long flex links across the hinge, so a complete diagram…

Schematic in PDF for the Toshiba Satellite L650, Inventec board 6050A2332301, revision MB-A02, about 891 KB.

Datasheet for the 2SA1737, a PNP bipolar transistor per the JIS 2SA prefix, supplied as a 40.2 KB PDF and catalogued in the schematic section.

The 2SC5588 is covered by this 332 KB PDF document. Apart from the part number the name gives no detail, so maker and revision are unknown until the file is opened.

RAR archive holding the PDF circuit diagram for MSI board MS-7846 at revision 2.1. The MS-number is MSI's internal motherboard code, printed on the PCB near the slots or…

Raspberry Pi Model B+ schematics, version 1.2, an 81.2 KB PDF. The pages document the power input and protection, switching regulators, USB and Ethernet section, HDMI…

A 172 KB PDF labelled 2SC5174, filed under schematics, though the name points to a component datasheet rather than a board drawing.

Circuit diagrams for the BlackBerry 9530, the Storm touchscreen handset, supplied as a 783 KB RAR. No revision or board code appears in the name.

Schematic in PDF for the ASUS TUF-RTX3090-24G-GAMING card with the GA102 GPU, board CG132P at revision 1.01X.

Schematic PDF for the Quanta boards DALVACMB8D0 and DA0LVAMB8F0, sized 4.99 MB. These DA-prefixed codes follow the Quanta scheme, identifying Quanta as the ODM; the name…
