TRIA HC-MB-EV
The TRIA 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.
