Whenever handling a Q7-974 module, ground yourself through an anti-static wrist strap. Placement of the board on an anti-static
surface is also highly recommended.
1.4Safety
The Q7-974 module uses only extremely-low voltages.
While handling the board, please use extreme caution to avoid any kind of risk or damages to electronic components.
1.5 Electrostatic Discharges
The Q7-974 module, like any other electronic product, is an electrostatic sensitive device: high voltages caused by static electricity could damage some or all the
devices and/or components on-board.
1.6 RoHS compliance
The Q7-974 module is designed using RoHS compliant components and is manufactured on a lead-free production line. It is therefore fully RoHS compliant.
Always switch the power off, and unplug the power supply unit, before handling the board and/or connecting cables or other boards.
Avoid using metallic components - like paper clips, screws and similar - near the board when connected to a power supply, to avoid
short circuits due to unwanted contacts with other board components.
If the board has become wet, never connect it to any external power supply unit or battery.
Check carefully that all cables are correctly connected and that they are not damaged.

2.1Introduction
Q7-974 is a CPU module, in Qseven®format, based on the Intel®Atom family of System-on-Chips (SOCs), formerly coded as Bay Trail, CPUs, a series of Single/
Dual / Quad SOCs with 64-bit instruction set.
These SOCs embed all the features usually obtained by combination of CPU + platform Controller hubs, all in one single IC, which allows, therefore, the system
minimisation and performance optimisation, which is essential for boards with sizes so reduced as for Qseven®boards, which offers all functionalities of standard
PC boards in just 70x70mm.
The board is also available in an EXTREME configuration, with all the components mounted onboard certified for industrial temperature ranges (this configuration is
not available with the Celeron®processors).
The embedded memory controller allows the integration of up to 8GB of DDR3L Memory directly soldered onboard, speed up to 1333MHz (it depends on the SoC
used).
All SOCs embed an Intel®HD Graphics 400 series controller, which offer high graphical performances, with support for Microsoft®DirectX11, OpenGL 3.0,
OpenCL 1.2, OpenGLES 2.0 and HW acceleration for video decoding of H.264, MPEG2, MVG, VC-1, VP8 and MJPEG video standards (for H.264, MPEG2 and
MVG also HW encoding is offered). This embedded GPU is able to drive two independent displays, by using the interfaces available on Qseven®golden finger
connector and/or the VGA dedicated connector.
Mass Storage capabilities of the board include up to two external S-ATA channels, a standard SD interface and one optional SATA Flash Disk soldered on board.
Other than the interfaces already discussed previously, on Qseven®golden finger connector there are the signals necessary for the implementation of Gigabit
Ethernet, one USB 3.0 port, up to 5 x USB 2.0 ports, 18/24-bit Single/Dual Channel LVDS or embedded Display Port interface, HDMI or multi-mode DisplayPort
interface, 3 x PCI-Express x 1 lanes, HD Audio interface, I2C, SPI, LPC and SM buses, UART interface.
Interfacing to the board comes through a single card edge connector, whose pinout is defined by Qseven®specifications Rel.2.0. For external interfacing to
standard devices, a carrier board with a 230-pin MXM connector is needed. This board will implement all the routing of the interface signals to external standard
connectors, as well as integration of other peripherals/devices not already included in Q7-974 CPU module.
Please refer to following chapter for a complete list of all peripherals integrated and characteristics.

2.3Electrical Specifications
According to Qseven®specifications, Q7-974 board needs to be supplied only with an external +5VDC power supply.
5 Volts standby voltage needs to be supplied for working in ATX mode.
For Real Time Clock working and CMOS memory data retention, it is also needed a backup battery voltage. All these voltages are supplied directly through card
edge fingers (see connector’s pinout).
All remaining voltages needed for board’s working are generated internally from +5V_S power rail.
2.3.1 Power Rails meanings
In all the tables contained in this manual, Power rails are named with the following meaning:
_S: Switched voltages, i.e. power rails that are active only when the board is in ACPI’s S0 (Working) state. Examples: +3.3V_S, +5V_S.
_A: Always-on voltages, i.e. power rails that are active both in ACPI’s S0 (Working), S3 (Standby) and S5 (Soft Off) state. Examples: +5V_A, +3.3V_A.
_U: unswitched ACPI S3 voltages, i.e. power rails that are active both in ACPI’s S0 (Working) and S3 (Standby) state. Examples: +1.5V_U

2.3.2 Power Consumption
Q7-974 module, like all Qseven®modules, needs a carrier board for its normal working. All connections with the external world come through this carrier board,
which provide also the required voltage to the board, deriving it from its power supply source.
Anyway, power consumption has been measured on +5V_S power rail that supplies the board. For this reason, the values indicated in the table below are real
average power consumptions of the board, and are independent from those of the peripherals connected to the Carrier Board.
Power consumption in Suspend and Soft-Off States have been measured on +5V_A power rail. RTC power consumption has been measured on carrier board’s
backup battery when the system is not powered.
The current consumptions, written in the table of this page, have been measured using the following setups:

2.4 Mechanical Specifications
According to Qseven®specifications, board dimensions are: 70 x 70 mm (2.76”x 2.76”).
Printed circuit of the board is made of twelve layers, some of them are ground planes, for
disturbance rejection.
The MXM connector accommodates various connector heights for different carrier board
applications needs. Qseven®specification suggests two connector heights, 7.8mm and
7.5mm, but it is also possible to use different connector heights, also remaining compliant
to the standard.
When using different connector heights, please consider that, according to Qseven®
specifications, components placed on bottom side of Q7-974 will have a maximum height
of 2.2mm ± 0.1. Keep this value in mind when choosing the MXM connector’s height, if it is
needed to place components on the carrier board in the zone below the Qseven®module.
