1. INTRODUCTION
1.1 Purpose
This document is the Hardware Reference Manual for the Q7 Generic Carrier Card. This board is
fully supported by iWave Systems Technologies Pvt. Ltd. This Manual includes system setup,
debugging and provides detailed information on the overall design and usage of the Q7 Generic
Carrier Card from a Hardware Systems perspective.
1.2 Qseven Overview
The Qseven concept is an off-the-shelf, multi vendor, Single-Board-Computer that integrates all
the core components of a common PC and is mounted onto an application specific carrier
board. Qseven modules have a standardized form factor of 70mm x 70mm and have specified
pinouts based on the high speed MXM system connector that has a standardized pinout
regardless of the vendor. The Qseven module provides the functional requirements for an
embedded application. These functions include, but are not limited to, graphics, sound, mass
storage, network and multiple USB ports. A single ruggedized MXM connector provides the
carrier board interface to carry all the I/O signals to and from the Qseven module. This MXM
connector is a well known and proven high speed signal interface connector that is commonly
used for high speed PCI Express graphics cards in notebooks.
iWave Q7 carrier card incorporated with additional two 80pin expansion connectors to bring
the non standard Qseven interfaces to carrier card associated with iWave’s Qseven CPU
modules.

2.2 Qseven MXM Connector
The Qseven module utilizes a 230-pin card-edge connector that is also used for PCI Express
capable notebook graphics cards following the MXM specification. Therefore, this connector
type is also known as a MXM connector.
The MXM edge connector is the result of an extensive collaborative design effort with the
industry's leading notebook manufacturers. This collaboration has produced a robust, low-cost
edge connector that is capable of handling high-speed serialized signals.

2.3 SD/MMC Card Slot
The SD/MMC Card Connector (J5) is connected to the Secure Digital I/O interface of the MXM
connector. This card socket will support up to a 8-bit data transfer. It supports card detect
feature, by default card detect pin is high after inserting card to the socket this pin should go
low for proper card detection. The main power for the Card Socket is 3.3V. The SD Card slot can
be configured as SD or MMC card operation. The SD Card Slot supports full 8-bit parallel data
transfers and can support SDIO cards (Wi-Fi, BT, etc) designed to fit in a standard SD card slot.
SD/MMC slot is physically located on top of the board.

2.4 Debug Connectors
Q7 Generic Carrier Card provides a 9-Pin D-Sub Debug UART Connector and JTAG connector for
debugging. Both debug interfaces are sharing same signals from MXM connector, since MUX
select line is used to select either UART or JTAG. Q7 Generic Carrier Card provided jumper
option (J62) to select Debug ports. For further information on these signals refer section
“Manufacturing Signals”of Qseven spec R1.20. In default jumper will be open and UART will be
supported.

2.4.1 9-Pin D-Sub Debug UART
UART will be used for Debug purpose. This is not the full functional UART and supports only
Serial TX and RX signals. External RS232 Transceiver will be used to convert the Processor CMOS
UART Transmit signal into RS232 signals at the driver section and convert the RS232 receive
signals into CMOS signals at the Receiver section. This RS232 signals will be connected to 9-Pin
