SECOCQ7-mITX2.0
User Manual - Rev. First Edition: 1.0 - Last Edition: 1.0 - Author: S.B. - Reviewed by G.M.
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
out on a dual row, 17 pin, P2.54mm standard pin header, with the following pinout.

will therefore depend on the Qseven
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
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:
