VIA COMe-8X91 COM Express® Module

The VIA COMe-8X91 is a Type 10 COM Express® mini form factor module that combines an 800MHz VIA Eden® X2 dual-core processor with a VIA VX900 media system processor to deliver the optimum blend of performance and low power consumption for a wide variety of embedded system design applications such as gaming, industrial automation, medical, and digital signage.


The VIA COMe-8X91 measures just 84mm x 55mm, and fully complies with the COM Express® embedded form factor standard developed by the PICMG (PCI Industrial Computer Manufacturers Group). Designed for optimum flexibility, the module also offers multiple I/O and display connectivity options.


The VIA COMe-8X91 is compatible with Microsoft® Windows® 7 and WES 7, as well as most popular Linux distributions. A wide range of software development tools are available, including the VIA Smart ETK.


Customers can take advantage of a proprietary start-up kit including a multi-I/O evaluation carrier board or can utilize VIA’s extensive technical support in developing a custom baseboard.
