The
SBC-X255 is a standard PC/104+ compliant, single board
computer. It is implemented by CM-X255
module providing most of the functions, and SB-X255 carrier board
providing connectors and several additional functions. The rich
features set of the SBC-X255 is customizable according to the price /
performance targets of the user's application.
The SBC-X255 contains PC/104+ expansion
connectors which open it to the wide range of standard peripheral
cards. Furthermore, the SBC-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.

Resources page.

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. SBC-X255 content is the combination of features provided
by the attached CM-X255 and the features implemented on the SB-X255.
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.
