Lenovo B490 laptop schematic in PDF format, about 1.95 MB. The name includes the string la4801126410106, which looks like an internal reference or board identifier, but…

Nokia 2220 handset schematic as a 737 KB PDF file. The name carries only the model number, with no revision or board identification.

Small PDF of 92.1 KB filed under schematics, though its name is simply the part number 2SD1998, so it is almost certainly a component datasheet rather than a board…

A 166 KB PDF for the 2SD1904 transistor, listed here as a schematic but by its name almost certainly the manufacturer data sheet.

Component documentation for the 2SK2920, a 409 KB PDF filed under schematics in this index but almost certainly a part datasheet.

The 2SK2854 transistor is documented in this 125 KB PDF, indexed under schematics but almost certainly a datasheet. The name states only the part number.

A 291 KB PDF dedicated to the 2SK1830. The 2SK code is the Japanese JIS designation for N-channel field-effect transistors, so this is almost certainly a datasheet…

A 213 KB boardview in BVR format for the Apple iPad 2. The name gives no board number or Wi-Fi or cellular variant, so compare component positions with your board before…

Boardview file for the first-generation Apple iPad Air, BVR format, 214 KB. The name carries no board number or cellular variant, so compare the layout with the actual…

Only the part number 2SC4168 identifies this 150 KB PDF, which carries a schematic label but is almost certainly a component datasheet.

Specification document for the 2SC5549 transistor, a 205 KB PDF in the schematic category.

A 135 KB PDF identified only by the part number 2SC3787. While the index files it as a schematic, the JIS designation 2SC indicates an NPN bipolar transistor, which…

PDF document labelled as a schematic but named after the 2SC5387, a Japanese-numbered NPN bipolar transistor part number, so in practice it is almost certainly the…

Indexed under schematics, this 223 KB PDF takes its name from the JIS part number 2SC2960, an NPN bipolar transistor designation.

PDF document of 196 KB identified only by the part number 2SA2058. Under the Japanese JIS convention, 2SA parts are PNP bipolar transistors, so this is almost certainly…

PDF document for the 2SA1200, a part number in the Japanese JIS 2SA series, which designates PNP bipolar transistors.

A 28.6 KB PDF named after the 2SA1179, a PNP transistor under the JIS 2SA designation. With only a part number in the name, it is almost certainly a brief datasheet…

A 44.4 KB PDF titled 181nq, categorised as a schematic but almost certainly the datasheet for a high-current Schottky rectifier module family; no voltage suffix is…

Reference PDF for the 24LC16B, a 16 Kbit I2C serial EEPROM organised as eight blocks of 256 bytes.

Cellular network section of the Samsung SM-A11 schematic, saved as a 4.33 MB PDF. It covers the RF transceiver area, power amplifiers, antenna switches, filters and the…

Cellular network section of the Samsung Galaxy A02s (SM-A02S) schematic in PDF format, 3.70 MB.

Zipped BIOS or firmware binary named simply 8, offering no information on the device, board or version.

Second copy of a firmware image for the HP dv7-4025ew laptop, 2.00 MB in .bin format, also tagged lx8, a token that cannot be interpreted with certainty.

Archive of 607 KB labelled M101z, with no brand, board number or revision in the name. The code alone is not enough to identify the device with certainty, so the…

PDF for the bq24780S, a Texas Instruments battery charge controller used in many notebooks to manage adapter detection, charging and system power selection.

Archive listed as BIOS firmware for the Dell Inspiron 15-3543, but it is only 78 bytes.

Small Lenovo archive of 463 KB labelled LCD D153, a code that may identify a monitor or display model, though this is not certain.

RAR archive of 2.45 MB holding schematic and boardview data for the original Apple iPad mini (first generation).

Schematic for the ASUS Prime H310M-K R2.0 desktop motherboard, revision 1.01A, delivered as a PDF inside a RAR archive.

Apple iPad 4 boardview in BVR format, 233 KB, with no logic board number in the name. Load it in FlexBV or another viewer that reads BVR to see components, nets and pins…

PDF specification, 864 KB, for the VVX14P048M00 panel, with a 2015-07-10 date in the name and no explicit revision.

Wistron schematic for the Lenovo ThinkPad T550 and W550s, project LSZ-1, board 13251-1, supplied as a RAR archive.

Positivo firmware dump for Quanta board DASW6HMB8E0 revision E, with 31 and sw6mb00d0 in the name.

Compressed ZIP package, 9.29 MB, labelled for the MSI MS-6533 motherboard. The name carries no revision, document type or firmware version, so open the archive to see…

Archive named ASUS A7K, but only 71 bytes in size, far too small to hold a schematic, boardview or firmware image.

ZIP archive of 6.03 MB named DEL1202, classified as firmware; the name alone does not identify the device model, version or brand with certainty, so inspect the contents…

BIOS binary for an unnamed J1900 motherboard, labelled as tested in the archive name, compressed into a 3.90 MB RAR.

Tiny 480-byte RAR for LP156WH3 TL S2, an LG Display 15.6-inch laptop LCD panel. At this size it almost certainly holds the panel EDID data rather than a system BIOS.

RAR archive of 1.15 MB for the HP Compaq Presario CQ40 Intel version on the Compal LA-4103P board.
