Firmware archive whose name only says colorful, likely meaning the Colorful brand, without giving a model, board or version, so its contents have to be identified by…

The only detail in this 183 KB PDF name is the part number 2SD2461, indicating the datasheet for that transistor.

An 88.2 KB PDF titled 2SD1884, indexed in the schematic section but, judging by the bare part number, a datasheet for that transistor.

A 429 KB PDF titled 2SK2789 and stored among schematics, most likely the datasheet for that part.

Part documentation for the 2SK2628LS, a 28.6 KB PDF. The 2SK prefix places it in the Japanese JIS family of N-channel field-effect transistors, and the LS suffix denotes…

The 2SJ584LS is documented in this 42.9 KB PDF, placed in the schematic category but named as a single-part datasheet.

The 2sc4725 is the subject of this 56.8 KB PDF, categorised as a schematic. Since 2SC is the JIS designation for NPN bipolar transistors, the document is most probably…

PDF of 171 KB for the 2SC5199, the same size as several neighbouring 2SC519x entries, which hints at a shared document format or a combined sheet.

Named 2SC4599, this 129 KB PDF is filed with schematics but reads as a part-number datasheet for a JIS-designated device, where 2SC means an NPN bipolar transistor for…

Larger than most in this series at 254 KB, this PDF documents the 2SC4497 NPN bipolar transistor, the 2SC prefix being the JIS designation.

Indexed as a schematic, this 105 KB PDF actually carries a semiconductor part number, 2SC4406.

Component documentation for the 2SC3686, packaged as a 92.3 KB PDF and filed as a schematic.

Named after the 2SA1527 transistor, this 30.7 KB PDF appears in the schematic category though its content should be the datasheet for the part.

The 2SA1438 transistor is described in this 133 KB PDF, which the index files under schematics.

Transistor datasheet for the 2SA2070 in PDF format, roughly 189 KB. The 2SA prefix places it in the JIS category of PNP transistors for high-frequency use.

PDF documentation of the 1SV307 diode, about 69 KB and listed as a schematic. The part number follows the JIS 1SV pattern, which Toshiba uses for variable-capacitance…

Circuit schematic for the Dell Vostro 3300 laptop, a 1.05 MB PDF. No board number or revision is given in the file name, so read the title pages to identify which ODM…

Schematic in PDF format, 847 KB, identified only as M750 with no brand, device or revision stated in the name.

RAR package of 5.92 MB for the Compal LA-9981P board, revision R10 (1.0), named without a hyphen in the board code. The contents are not stated.

Archive with the uninformative label H0222-SE, 401 KB in RAR format, giving no device brand, model or content type.

RAR archive labelled H0222-2, 427 KB in size, without any brand, model or document type in its name.

Schematic package for board GK5CXXT, a 1.32 MB RAR whose name indicates a PDF inside. The GK5C-style code resembles Tongfang barebone board naming, but no laptop brand…

Schematic archive of about 946 KB labelled J730F, a model code matching the Samsung Galaxy J7 Pro, although the brand is not in the file metadata.

BIOS archive for an X453MA, an ASUS model code, though the brand is not stated; labelled ok new, suggesting a fresh dump confirmed working.

Boardview for the Sony VAIO SVF15 laptop, Quanta board DA0HK9MB6D0 with project code HK9, in a 96.9 KB ZIP.

PDF circuit diagram for the Quanta-made motherboard DAZ8EMB18A0, revision A, the final letter of the board code.

Schematic in PDF for the Quanta board DAZ8VMB18D0, revision D. Quanta board numbers start with DA and end with a revision letter, which here is D.

Boardview for a board identified only as GH5AD2D, version 1.0; the name gives no brand or device.

Boardview in BRD format for a board labelled R23-MB-D, compressed into a 128 KB RAR. No brand is stated, and the label alone does not identify the device.
