ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

Introduction
The Q7B300 is a new development baseboard for embedded Qseven Module and fully
compliant with the Qseven Specification 2.0 standard. The Qseven is an open industry
standard for Qseven modules, designed to be future proof and to provide a smooth transition
path from legacy parallel interfaces to LVDS interfaces. In addition to the standard output
signals for converting, Q7B300 provides one PCI-Express Mini Card socket and one SD card
slot for expansion purposes.
This board supports various I/O features: display interfaces (DP/eDP and LVDS), one
Gigabit/Fast Ethernet, HD audio codec, two SATA-600, two USB 3.0 and two RS-232
connectors.
With Q7B300, customers can develop their own applications and upgrade the system
configuration in advance to meet faster time-to-market.

2.3 Installing Qseven Module and Thermal Solution
For thermal dissipation, a heatsink enables the components on the Qseven module to
dissipate heat efficiently. All heat generating components are thermally conducted to the
heatsink in order to avoid hot spots. Below images illustrate how to install the heatsink.
1. There is a protective plastic covering on the thermal pads. This must be removed before
the heatsink can be mounted.
2. Each heatsink is designed for a specific Qseven module. The thermal pads on the
heatsink are designed to make contact with the necessary components on the Qseven
module. When mounting the heatsink you must make sure that the thermal pads on the
heatsink make complete contact (no space between thermal pad and component) with
the corresponding components on the Qseven module. This is especially critical for
Qseven modules that have higher CPU speeds (for example 1.46GHz or more) to ensure
that the heatsink acts as a proper thermal interface for cooling solutions.
3. This CPU module has four assembly holes for installing heatsink plate. Fix the heatsink
plate to the Qseven module and install to carrier board. Be careful not to over-tighten the
screws.

2.4 Jumper Settings
Jumper is a small component consisting of jumper clip and jumper pins. Install jumper clip on 2
jumper pins to close. And remove jumper clip from 2 jumper pins to open. Below illustration
shows how to set up jumper.
Properly configure jumper settings on the Q7B300 to meet your application purpose. Below
you can find a summary table of all jumpers and onboard default settings.
Note
Once the default jumper setting needs to be changed, please do it under power-off
condition.
