  • The "SB option" column specifies the SB-SOM-T43 carrier board P/N code required for a particular feature. The "CM option" column specifies the CM-T43 P/N code required for a particular feature. SBC-T43 feature-set is a combination of features provided by the attached CM-T43 and the features implemented on the SB-SOM-T43. For a particular feature to be present, both the CM and SB options of that feature must be implemented.
  • "+" means that the feature is always available, regardless of P/N code.
