Signal Pin# Pin Type Pwr Rail /Tolerance DFI-FS700 Series Carrier Board Description
CAN0_TX 129 O CMOS 3.3V/3.3V CAN (Controller Area Network) TX output for CAN Bus channel 0.
In order to connect a CAN controller device to the Qseven module's CAN bus it is necessary to add transceiver hardware to the carrier board.
CAN0_RX 130 I CMOS 3.3V/3.3V RX input for CAN Bus channel 0. In order to connect a CAN controller device to the Qseven module's CAN bus it is necessary to add transceiver hardware to the carrier board.
Signal Pin# Pin Type Pwr Rail /Tolerance DFI-FS700 Series Carrier Board Description
PWGIN 26 I CMOS 5V/5V High active input for the Qseven® module indicates that all power rails located on the carrier board are ready for use.
PWRBTN# 20 I CMOS 3.3V Standby Power Button: Low active power button input. This signal is triggered on the falling edge.
Signal Pin# Pin Type Pwr Rail /Tolerance DFI-FS700 Series Carrier Board Description
RSTBTN# 28 I CMOS 3.3V/3.3V Reset button input. This input may be driven active low by an external circuitry to reset the Qseven module.
BATLOW# 27 I CMOS 3.3V Suspend/3.3V Battery low input. This signal may be driven active low by external circuitry to signal that the system battery is low or may be used to signal some other external battery management event.
WAKE# 17 I CMOS 3.3V Suspend/3.3V External system wake event. This may be driven active low by external circuitry to signal an external wake-up event.
SUS_STAT# 19 O CMOS 3.3V Suspend/3.3V Suspend Status: indicates that the system will be entering a low power state soon.
SUS_S3# 18 O CMOS 3.3V Suspend/3.3V S3 State: This signal shuts off power to all runtime system components that are not maintained during S3 (Suspend to Ram), S4 or S5 states.
The signal SUS_S3# is necessary in order to support the optional S3 cold power state.
SUS_S5# 16 O CMOS 3.3V Suspend/3.3V S5 State: This signal indicates S4 or S5 (Soft Off) state.
SLP_BTN# 21 I CMOS 3.3V Suspend/3.3V Sleep button. Low active signal used by the ACPI operating system to transition the system into sleep state or to wake it up again. This signal is triggered on falling edge.
LID_BTN# 22 I CMOS 3.3V Suspend/3.3V LID button. Low active signal used by the ACPI operating system to detect a LID switch and to bring system into sleep state or to wake it up again.
Open/Close state may be software configurable.
Signal Pin# Pin Type Pwr Rail /Tolerance DFI-FS700 Series Carrier Board Description
WDTRIG# 70 I CMOS 3.3V/3.3V Watchdog trigger signal. This signal restarts the watchdog timer of the Qseven module on the falling edge of a low active pulse.
WDOUT 72 O CMOS 3.3V/3.3V Watchdog event indicator. High active output used for signaling a missing watchdog trigger. Will be deasserted by software, system reset or a system power down.
I2C_CLK 66 I/O OD CMOS 3.3V/3.3V PU 4.7K to 3.3V Clock line of I²C bus.
I2C_DAT 68 I/O OD CMOS 3.3V/3.3V PU 4.7K to 3.3V Data line of I²C bus.
SMB_CLK 60 I/O OD CMOS 3.3V Suspend/3.3V PU 4.7K to 3.3V Clock line of System Management Bus.
SMB_DAT 62 I/O OD CMOS 3.3V Suspend/3.3V PU 4.7K to 3.3V Data line of System Management Bus.
SMB_ALERT# 64 O CMOS 3.3V/3.3V System Management Bus Alert input. This signal may be driven low by SMB devices to signal an event on the SM Bus.
SPKR/GP_PWM_OUT2 194 O CMOS 3.3V/3.3V Primary functionality is output for audio enunciator, the“speaker” in PC AT systems. When not in use for this primary purpose it can be used as General Purpose PWM Output.
BIOS_DISABLE#/BOOT_ALT# 41 I CMOS 3.3V/3.3V PU 10K to 3.3V Module BIOS disable input signal. Pull low to disable module's on-board BIOS.
Allows off-module BIOS implementations. This signal can also be used to disable standard boot firmware flash device and enable an alternative boot firmware source, for example a boot loader.
