Introduction
Connect Tech’s COM Express Carrier Boards are small feature rich, super flexible carrier boards that
integrate with any industry standard type II COM Express module. These bus-independent carrier boards
offer easy connection to SATA HDD, USB, Ethernet, HDMI Video, LVDS Video, VGA video, RS-232 and
RS485 serial.
Connect Tech’s COM Express carrier boards are ideal for compact and high performance computing
applications in mobile entertainment, kiosks, digital signage, automation, ROVs and gaming applications.
ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any circuit
board assemblies including Connect Tech COM Express carrier
assemblies, it is recommended that ESD safety precautions be
observed. ESD safe best practices include, but are not limited
to:
Leaving circuit boards in their antistatic packaging
until they are ready to be installed.
Using a grounded wrist strap when handling circuit
boards, at a minimum you should touch a grounded
metal object to dissipate any static charge that may be
present on you.
Only handling circuit boards in ESD safe areas, which
may include ESD floor and table mats, wrist strap
stations and ESD safe lab coats.
Avoiding handling circuit boards in carpeted areas.
Try to handle the board by the edges, avoiding contact
with components.
