| Integration Efforts v.s. Application Flexibilities Integration efforts heavily rely on application flexibilities. The key difference between embedded boards and embedded modules is how their onboard features are accessed and how they incorporate application specific features. Embedded board SBCs offer a dedicated connector for each onboard I/O subsystem which allows the connection to the appropriate peripheral or peripheral access point in a system through a cable. A module SBC steers all of its onboard I/O signals to board-to-board style connectors or pin headers and access to onboard I/O subsystems is achieved through an application-specific cable and add-on board (PC/104) or carrier board (COM). "It does not fit!" This sentence is often heard when CPU boards for industrial applications are to be selected. Usually the problems are in the mechanics, placement of headers, and missing extra functionality. The traditional way to solve this -- a full custom board design-- is very time consuming and costly. Use one of the standardized PC/104 modules or computer on modules is the solution for that. With embedded board SBCs, the integration effort is small. With PC/104 modules, usually connect cables to enclosure is good enough and use off-the-shelf add-on board for extra functions. While with computer on modules, the custom features are integrated into the carrier board design. |
