Embedded Module TQMxE38C: COM Express™ Compact Module (Type 6)


The TQ mini module TQMxE38C 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 6 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 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.
