up to 25 Gbit/s per lane. All I/O signals are mapped to two high density, high speed and low profile connectors on the bottom side of the module. COM-HPC employs a mezzanine-based approach. The COM modules plug into a carrier or base board that is typically customized to the application. Over time, the COM-HPC mezzanine modules can be upgraded to newer, backwards-compatible versions. COM-HPC targets Industrial, Military/Aerospace, Gaming, Medical, Transportation, IoT, and General Computing embedded applications and even scales up to RAM and performance hungry server or edge server applications.
