Recommendations and Considerations
The manual emphasizes the importance of adhering to Qseven® specifications and provides guidance on selecting appropriate components and configurations for optimal performance. It also highlights the need for independent analysis and judgment in using the provided schematics and material.

Ethernet Connection
For Ethernet connections at 10/100 Mbps, only MDI0 and MDI1 differential lanes are necessary. Unused pairs can be left unconnected.

S-ATA Signals
The Q7-928 module has one S-ATA interface managed by the i.MX6 processor, available only on i.MX6 Quad and Dual versions. Key signals include transmit and receive differential pairs and an activity LED signal.

USB Interface Signals
The i.MX6 processor supports four USB 2.0 controllers. Core #0 supports OTG capabilities, while Core #1 operates in Host mode. Cores #2 and #3 are unused. Overcurrent detection and EMI/ESD protection are necessary for proper USB management.

SDI/O Interface Signals
The i.MX6 processor offers multiple SDIO interfaces for various storage options. The SDI/O port supports multiple communication modes, with signals for card detection, clock, command, and data transfer.

Audio Interface Signals
The Q7-928 module supports AC’97 audio format with signals for synchronization, reset, bit clock, and data transfer. These signals must connect to an AC’97 Audio Codec on the carrier board.

LVDS Flat Panel Signals
The i.MX6 processor includes an LVDS Display Bridge for connecting displays. It supports various configurations for single and dual-channel outputs, with signals for data pairs, clock, and power management.

HDMI Interface Signals
The processor includes an HDMI Tx module for HDMI 1.4a compliant displays. Signals include TMDS differential pairs and control lines for data, clock, and hot plug detection.

LPC/GPIO Interface Signals
The module supports LPC Bus interface or GPIOs, with signals for data bus, clock, frame, DMA request, and IRQ request. GPIOs can be programmed using SECO APIs or Linux File System.

SPI Interface Signals
The i.MX6 processors offer up to four SPI interfaces for connecting EEPROMs and Serial Flash devices, supporting speeds up to 20MHz.

CAN Interface Signals
The Q7-928 module supports a CAN interface compliant with CAN specifications 2.0 part B. It requires a CAN Bus Transceiver on the carrier board for connection to a CAN Bus. The CAN0_TX and CAN0_RX signals operate at +3.3V_S.

Power Management Signals
The module includes several power management signals such as PWGIN, PWRBTN#, RSTBTN#, BATLOW#, WAKE#, SUS_STAT#, SUS_S3#, SUS_S5#, SLP_BTN#, and LID_BTN#. These signals manage power states and transitions, with specific voltage levels and resistor configurations.

Miscellaneous Signals
Additional signals include WDTRIG#, WDOUT, BOOT_ALT#, GPIO_6, GPIO_19, GP_TIMER_IN, GP_PWM_OUT1, GP_PWM_OUT2, SMB_CLK, SMB_DAT, GP0_I2C_CLK, and GP0_I2C_DAT. These signals serve various functions such as watchdog management, boot configuration, and general-purpose I/O.

Manufacturing Signals
The Q7-928 module includes JTAG signals for programming the internal FPGA, accessible via MFG_NCx pins. These signals are reserved for manufacturing and should not be used by customers. The module can be configured to provide i.MX6 JTAG access if needed.

Thermal Design
Effective thermal management is crucial for the Q7-928 module. A heatspreader is recommended to transfer heat to external cooling solutions. The choice of cooling solution should consider processor workload and system environment. SECO provides specific heatspreaders and heatsinks for different module versions.
