What is an Express Card Module?An ExpressCard module is a small, modular add-in card technology intended to be used in desktop and mobile computing platforms.![]() The ExpressCard solution accommodates the replacement of conventional parallel buses for I/O devices with scaleable, high-speed serial interfaces. Two classes of serial interfaces are implemented by this solution, PCI Express, a high performance, integrated I/O interconnect solution, and USB for the ease of upgrading PC Card technologies and integrating popular external peripheral functionality via the ExpressCard module form-factor. Two standard module formats are specified: an ExpressCard/34 module and an ExpressCard/54 module. The ExpressCard solution is designed to support a universal slot configuration that allows either ExpressCard/34 or ExpressCard/54 modules to function in the same slot. Host solutions that implement slots that only support ExpressCard/34 modules are also allowed by this standard. The ExpressCard architecture is based on an extensible, modular implementation, allowing multiple slots (see Figure 2). In any multi-slot host implementation, all slots provide equivalent I/O interface functionality. Both module formats afford access to the same I/O interface performance and source power although the larger ExpressCard/54 module affords the application nominally 140% the internal volume and 160% the thermal dissipation capacity over the ExpressCard/34 module. There are two formats of the standard ExpressCard modules in this specification: the ExpressCard/34 module characterized by its 34 mm width and the ExpressCard/54 module characterized by its 54 mm width. ![]() ![]() Many new laptops are now including ExpressCard, such as the new Apple MacBook Pro. ![]() What EVDO Cards Are Available in ExpressCard Format?Currently none. This list we be updated as more information becomes available. Related Articles: |
