SBC-i686 Board

In EOL phase, see expected life time. Users are advised to consider SB-iGLX as replacement.



The SBC-i686 is a standard PC/104+ compliant, single board computer. It is implemented by CM-i686B module providing most of the functions, and SB-i686 carrier board providing connectors and several additional functions. The rich features set of the SBC-i686 is customizable according to the price / performance targets of the user’s application.

The SBC-i686 contains a PC/104+ expansion connectors which opens it to the wide range of standard peripheral cards. Furthermore, the SBC-i686 contains a PCMCIA / Card Bus controller and slots.  A PCMCIA card may be inserted and secured in the slot, with no additional mechanical means. Off-the-shelf PCMCIA modules can extend the system with capabilities such as a larger solid state disk, modem, and wireless LAN.

Block diagrams



“SB Option” column specifies the P/N code of SB-i686 required to have the particular feature.  “CM Option” column specifies the P/N code of CM-i686B required to have the particular feature. The SBC-i686 content is the combination of features provided by the attached CM-i686B and features implemented on SB-i686. To have the particular feature, both CM and SB options of that feature must be implemented.
“+” means that the feature is always available, regardless of P/N code.
