We are collecting information about hardware interfaces of modern and obsolete devices, including pinouts of ports, expansion slots, and other connectors of computers and common electronic devices. This information is essential for everyone who wants to investigate insights of modern computer hardware, explore the ways of how it's works, design computer dependent devices.

Our handbook includes more than 1000 documents :

• Pinouts of computer hardware components, internal connectors, buses and input/output ports (i.e. PC Serial port pinout, PCI Bus ).
• Pinouts and brief information about some common computer hardware interfaces (such a RS232 interface, USB, ATA/IDE).
• Pinouts of audio/video connectors (i.e. S-Video connector or VGA connector pinout)
• Pinouts of cellular phones, consumer audio/video hardware and over devices (i.e. Nokia Pop port pinout or Apple iPod, iPhone, iPad Dock connector)
• Schemes of computer peripherals and other devices cables and converters (i.e. USB to RS232 serial converter schematic)
• Layout and numbering scheme of common and device-specific connectors

All documents are free and available online in english and russian languages.

The hardware investigated here includes modern (PC, Apple Macintosh,...) and obsolete (Atari, Commodore, MSX,...) computers, mobile phones and some other devices (like GPS units, PDA,...).
Most of documents have been created by our visitors, written by me or collected from public-available internet sources (with link(s) to origin(s) included). Feel free to contact webmaster if you believe that any of this publications affects your author's rights.

Content of this site is a result of our collective work. Something left uncovered? You may add new pinouts! Submit your information to pinout helper and webpage will be created with YOUR knowledge.

You are welcome to ask any questions about pinouts, connectors and wiring at the forum.

Feel free to correct existing documents, add explanations, fix errors, suggest related links at this forum (don't forget to include title of document(s) affected).
In addition, you may submit your suggestions and comments via guestbook.

Please, link to us if our information was useful for you!

I'm grateful to Joakim Ogren and Hardware Book team for Hardware Book project and a lot of information.
