 The SB-X255 is a standard PC/104+ compliant, single board computer. It uses an CM-X255 module to implement most of the provided functions and also implements several additional important functions on-board. The rich set of features provided by the SB-X255 is customizable according to the price / performance targets of the user's application.

The SB-X255 contains PC/104+ expansion connectors which open it to the wide range of standard peripheral cards. Furthermore, the SB-X255 contains a PCMCIA 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.

SB-X255 Features

The "SB Option" column specifies the P/N code of SB-X255 required to have the particular feature. The "CM Option" column specifies the P/N code of CM-X255 required to have the particular feature. SB-X255 content is the combination of features provided by the attached CM-X255 and the features implemented on the SB-X255 itself. To have the particular feature, both the CM and SB options of that feature must be implemented.
"+" means that the feature is always available, regardless of P/N code.
