 PC/104+ & ATX Boards                

PC/104+ boards are small computers packed into the industry standard PC/104+ form factor. Each PC/104+ board is a combination of specific baseboard (SB) and matching computer-on-module (CM) implementing of most of the functions.

Mini-ATX boards are small computers packed into the industry standard Mini-ATX form factor. Each Mini-ATX board is a combination of ATX baseboard, the same in all products, and the specific computer-on-module implementing of most of the functions.

SBC-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. 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.
