COM-HPC Client Carrier

The MSC HC-MB-EV is intended for design teams that require an easy and fast enablement of COM-HPC based solutions for lab evaluation, rapid prototyping and application development. Engineers can use it as a reference design for developing their own COM-HPC platform. The COM-HPC Client carrier provides a rich set of COM-HPC Client interfaces routed to the module socket including PCIe and PEG ports, DDI and eDP graphics interfaces, and high speed I/O like USB and SATA. COM-HPC Client modules of either Size A, B and C can be installed on the carrier.
