  • Base


    The TQ mini module TQMxE38M enables the implementation of powerful but also economical x86 based systems based on the international established PICMGTM standard COM ExpressTM Mini (COM.0 R2.1). At the type 10 compliant pin out the user has access to all fundamental interfaces of the CPU. For that all capabilities of the Intel® AtomTM processor could be used. The direct access to the interface like digital display interface (DDI) / embedded DisplayPort (eDP) and the USB device interface gives the user the unlimited freedom to use the features of the CPU in most suitable way for his application. The compact and robust design as well as the option of formal coating extends the use cases to applications within rugged industry, railway and aviation environments. Based on the very low power consumption and the extended temperature support it is also possible to realize outdoor applications in an easy and reliable way.
