Archive of high-definition photographs of the ASUS X551CA motherboard, revision 2.2 as given in the name.

RAR archive named simply EC, about 10 MB, listed as BIOS or firmware. The name gives no model or board number, so its contents must be checked before use.

Raw BIOS dump of 16 MB named only 08A3C, which gives no clear brand, model or board number. Such codes can be a system or board ID, but that cannot be confirmed here.

BIOS dump for the Lenovo IdeaPad 3-17ADA05, stored as a raw 8.00 MB .bin, matching a 64 Mbit SPI flash chip.

Schematic PDF shared by the ASUS X407UAR, X407UBR and X407UFR laptops, which are variants built on a common platform.

Schematic PDF identified only by the codes H0225-3, 48.4KH17.031 and LDB1; the name does not state a laptop brand or model.

Firmware dump for the HP EliteBook x360 1030 G2, with 5CG73211NT in the name, which looks like the serial number of the unit it was read from.

BIOS image for the Lenovo ThinkPad X1 Carbon 6th Gen, machine type 20KG, a 5.70 MB RAR copy marked (2) to distinguish it from a similarly named file.

Lenovo firmware dump tied to motherboard NM-D341, with the additional code HYG60HX4B0 in the name, likely a board label identifier, compressed as a 9.68 MB RAR.

Reference PDF, 181 KB, for the KA2923, an IC from the KA prefix series; the name contains only the part number and does not state its function, so that must be read from…

Datasheet for the 2N2222, the long-established general-purpose NPN switching transistor, as a 79.5 KB PDF.

PDF covering the BF458 and BF459 transistors, a compact 49.2 KB file listed as a schematic but most likely a shared datasheet.

Datasheet for the BD135 transistor in a 51.0 KB PDF, likely the same family document that also covers related types in the series.

Datasheet for the BC328 PNP transistor in PDF format, 53.5 KB, the same size as the combined BC327 and BC328 sheet in this index.

The name 3LP01S identifies this 28.1 KB PDF only by a component-style code with an S suffix; no laptop, board number or revision appears.

Short 28.6 KB PDF filed under schematics with the name 3LP01N, a code that resembles a discrete semiconductor part number with an N suffix.

The 2SK545 is covered by this 80.4 KB PDF, filed as a schematic but most likely a datasheet because 2SK numbers identify N-channel field-effect transistors in the…

The 2SK427 document is a 226 KB PDF filed as a schematic, but the 2SK prefix marks an N-channel field-effect transistor in the JIS numbering scheme, so it is effectively…

A 140 KB PDF named after the semiconductor 2SJ563, listed in the index under schematics.

The name of this 97.3 KB PDF gives nothing beyond 2SJ277, a JIS-style designation in which 2SJ marks a P-channel FET.

Filed as a schematic, this 93.5 KB PDF is identified solely by 2SJ274. The Japanese JIS 2SJ prefix stands for a P-channel field-effect transistor, so the content is most…

Named simply 2SJ226, this 84.5 KB PDF refers to a JIS-registered P-channel FET and most likely contains the part datasheet, even though it sits in the schematic section.

PDF reference, around 129 KB, covering two power ICs identified by marking codes: Qq for the SY8386BRHC and 3a for the SY8388C3RHC.

An archive in RAR format, roughly 959 KB, for the Xiaomi Mi 4S phone. The name lists only the model, with no indication of document type, PCB number or revision, so…

Meizu MX5 archive in RAR format, 881 KB, whose name identifies only the phone model and not the file type inside.

Boardview in BVR format for the iPhone 5C main logic board, 266 KB uncompressed. It opens in boardview software that reads BVR files and shows both sides of the PCB with…

Listed under schematics but named only after a part number, this 91.6 KB PDF most likely holds the datasheet for the 2SC4188 transistor.

The 2SC4121 part number is the whole name of this 89.5 KB PDF; although typed as a schematic, it should be the datasheet for that NPN bipolar transistor, as the Japanese…

PDF of 47.7 KB named 2PD602A, apparently issue 4 of the document. The name identifies a part rather than a product or board, which points to a discrete semiconductor…

A small 26.9 KB PDF in the schematic category, named only with the part number 2N6519 from the JEDEC 2N registration series.

Zener diode datasheet covering the range from 1N4728A to 1N4764A, an 88.2 KB PDF. This 1 W axial Zener series spans a wide range of nominal voltages, each part number…

A 54.5 KB PDF filed as a schematic and identified only by the short code 51HQ, with no brand, model or revision stated.

Filed under schematics, 35clq045 is a 47.8 KB PDF whose name reads like a discrete part number; it does not state any device, manufacturer or revision.

Part-number-style PDF, 176 KB, labelled 27lc040 and listed here as a schematic. The pattern matches the 27-series UV or OTP EPROM family, with LC typically denoting a…
