XC1 - ESMexpress COM Carrier Board (Product Discontinued)

ESMexpress is a Computer-On-Module which together with an application-specific carrier board forms a semi-custom solution for industrial, harsh, mobile and mission-critical environments.

The XC1 is an evaluation and development platform that can be usedtogether with any type of ESMexpress module. Thus, the XC1 provides physical interfaces and connectors for nearly all of the modern serial standard I/Os routable from the ESMexpress connectors to the carrier board. The XC1 comes with one ESMexpress slot and eight additional PCI Express card slots. The functionality of all connectors depends on the ESMexpress module used on the XC1. It supports standard ATX form factor and can therefore operate in a PC system. Additional 4 GB of USB-driven Flash disk for application storage complement the memory configuration that is already available on the different ESMexpress modules.

For a first evaluation of the functions and performance of the ESMexpress module of choice we strongly recommend to use the XC1. Further useful accessories include an external PSU and an ESMexpress to COM Express adapter.
