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.


  • Socket for COM-HPC™ Carrier supporting Client Size A, B, C modules
  • PCI Express x16 slot (useable as PEG or general PCIe)
  • Three PCI Express slots 1×4
  • Support for PCIe Gen 3 and 4
  • Two SATA connectors
  • M.2 socket for mass storage and AI modules
  • M.2 socket for I/O purposes (3rd party modules e.g. Wi-Fi, Bluetooth)
  • Two USB 3.1 Gen 1, Gen 2 connectors
  • Two 1G/10G-BaseT connectors (RJ45)
  • Two DisplayPort connectors
  • One eDP connector
  • HD audio codec
  • Various additional COM-HPC™ specific interfaces
  • Power supply via ATX-style power connector or 12V-only power jack
  • Wide power input range
  • Size 244mm x 244mm (microATX)
