Please notice that signal 1-Wire_Bus will be available depending on configuration of Jumper JP6,
as already described in paragraph 3.3.5. If that Jumper is set in position 1-2, then on pin 7 of
connector CN24 there will be available the signal GP_1-Wire_Bus coming out from Qseven
®
connector pin 124. Please remember that the signal effectively available on that pin depends on
the Qseven
®
module used and, eventually, on BSP programming.
3.3.18 SPI Flash socket
In case in your application is needed an external SPI Flash, on the carrier board it is provided an 8-
pin SOIC socket for the housing of SPI Flashes.
Socket is type LOTES p/n ACA-SPI-004-K0 or equivalent, p. 1.27mm, with the following pinout:

3.3.19 LPC Pin Header
It is possible to increase furthermore connectivity possibilities of SECOCQ7-mITX2.0 carrier board
using the LPC/GPIO signals coming out form Qseven
®
golden finger connector, which are carried
out on a dual row, 17 pin, P2.54mm standard pin header, with the following pinout.

According to Qseven

specifications rel. 2.0, on pins 185÷192 of the Golden finger connector there
can be LPC interface of GPIO signals. Please be aware that the interface available on CN23 pins
will therefore depend on the Qseven
®
module used and, eventually, on BSP programming.
3.3.20 FAN Connector
SECOCQ7-mITX2.0 carrier board is able to manage both +5VDC and +12VDC fans, with speed
control (speed control can be used only if your Qseven
®
module supports this feature, using
signals FAN_TACHOIN and FAN_PWMOUT).
For the connection of the fan, a connector type MOLEX 22-27-2031 or equivalent is available, with
the following pinout:
