JTAG is a standard for device testing ports found on the PCBs of many devices. Finding the pads and pinouts for these ports allows hackers to gain access to the embedded systems, their on-board debugging tools, etc., effectively providing a back door. But determining the JTAG pinouts can be a time-consuming and frustrating process. To help in this, a German hardware hacker named Hunz has created the JTAG Finder, an automatic JTAG pin-out detector, using an 8bit AVR ATmega16/32L microcontroller. Details of the project, and a call for others to get involved, can be found on the JTAG Finder wiki. He also wants to build a JTAG Found database of known device pinouts.

    This JTAG pinouts archive seems very interesting and I suggest to post any discovered pinout on the public AllPinouts archive (http://www.allpinouts.org).

    AllPinouts is created with the same MediaWiki software that was developed for the Wikipedia project and allows registered users to contribute and improve the website. All text is available under the GNU Free Documentation License (GFDL) and may be distributed or linked accordingly.

    AllPinouts is a free content project that collects information about hardware interfaces of modern and obsolete hardware, including pinouts of ports, expansion slots, and other connectors of computers and different digital devices (i.e. Cellular Phones, GPS, PDA, Game Consoles, etc.). AllPinouts archive already contains hundreds of pages organized into three main categories (Connectors, Cables, Adapters) and several subcategories.
