Schematic of the small sub-board for the Redmi K40 Pro smartphone, a 100 KB PDF. The small board in phones usually carries the USB charging port, microphone and related…

Component location map for the small sub-board of the Redmi K40 Pro smartphone, provided as a 95.4 KB PDF.

Schematic for the Compal LS-6852P, revision R1.0, in a small 23.5 KB RAR archive. Compal uses the LS- prefix for daughter boards such as USB, audio, power-button or…

Compal LS-6094P schematic, revision R1.0, in a small 40.8 KB RAR archive. Compal uses LS-prefixed numbers for daughter boards, such as power-button, USB, audio or…

Compal LS-6583P schematic, revision R1.0, in a small 29.3 KB RAR archive. Compal's LS prefix usually denotes a small daughterboard such as a power-button, USB, audio or…

Compal LS-6854P schematic at revision R1.0, in a very small 19.8 KB RAR. Compal uses the LS prefix for small daughterboards such as power-button, USB, audio or…

Schematics for the Nokia N500 smartphone in a small 261 KB RAR archive. The name carries no revision or RM type code, so verify the contents correspond to your unit.

Small PDF of 26.5 KB named 5HP01SS, listed as a schematic yet evidently referring to a single semiconductor part rather than a board.

The 223 KB PDF called 93lc46 refers to a small Microwire serial EEPROM and is likely the datasheet rather than a board schematic.

Small 33.9 KB PDF datasheet for the 2N3415, a JEDEC-registered 2N-series transistor, labelled as a schematic. The name gives only the part number.

Small 25.5 KB PDF for the 2SA1816, bearing an _E suffix in its name and catalogued as a schematic. Under JIS rules the 2SA prefix marks a PNP bipolar transistor.

Larger 440 KB PDF for the 2N7002, tagged Sam in the name, which likely refers to the issuing manufacturer, though the file does not spell it out.

Compact 29.9 KB PDF titled with the part number 2sk301 only. The 2SK prefix under JIS rules marks an N-channel FET, so this is best treated as a component data sheet…

Small 21.1 KB PDF for the 2SC945 transistor, with UTC in the name identifying the Unisonic Technologies version of this widely used small-signal NPN part.

Compact 26.2 KB PDF for the 1SS383T, smaller than most files in this series and filed as a schematic.

A 71.2 KB PDF with data for the 2N2222, filed with schematics in this index. The 2N2222 is a staple NPN small-signal transistor used for switching relays, LEDs and logic…

PDF datasheet for the 1N5711, a small-signal Schottky barrier diode often used for fast switching and RF detection, placed in the schematic category.

Small PDF, 73 KB, documenting the 24LC01B, a 1 Kbit I2C serial EEPROM, the smallest common member of the 24LC family.

Smallest of the batch at 30.8 KB, the PDF named 2SC5607 is presumably a concise datasheet for that NPN transistor despite being labelled a schematic.

Larger 546 KB PDF datasheet covering the 2N5400, a high-voltage PNP small-signal transistor; the size suggests a scanned or multi-part document.
