PLT_RST#: Reset Signal that is sent from the SoC to all PCI-e devices available on the board
(i.e. the GbE controller, the PCI-e based SSD modules plugged in the CN20 slot and the
connectivity modules plugged in CN19 slot). It is a 3.3V active-low signal.
PCIe_REQ3#: PCI Express Clock Request Input, active low signal. This signal shall be driven
low by any module inserted in the connectivity slot, in order to ensure that the SoC makes
available the reference clock.
SUS_CLK: 32.768kHz Clock provided by the UDOO x86 board to the module plugged in
the slot CN17. +3.3V_A electrical level.
BT_DISABLE#: Bluetooth module disable, active low signal, +3.3V_A electrical level. This
signal can be used to disable Bluetooth functionalities of any connectivity module plugged in
CN16 Slot. This signal is also managed by BIOS (see par. 4.5,
“
Bluetooth on M.2
”
).
WIFI_DISABLE#; WiFi module disable, active low signal, +3.3V_A electrical level. This signal
can be used to disable WiFi functionalities of any connectivity module plugged in CN16 Slot.
This signal is also managed by BIOS (see par. 4.5,
“
WiFi on M.2
”
)

FAN connector
Depending on the usage model of UDOO x86, for critical applications/environments on UDOO x86 it is available a 3-pin single
line SMT connector for an ex12V
DC
FAN.
The Connector is a type MOLEX 53261-0371 or equivalent, with pinout shown in the table on the left.
Mating connector: MOLEX 51021-0300 receptacle with MOLEX 50079-8000 female crimp terminals.
Please be aware that the use of an external fan depends strongly on customer
’
s application/installation.
FAN_POWER: +12V_A derived power rail for FAN.
FAN_TACHO_IN: tachometric input from the FAN to the embedded microcontroller, +3.3V_S electrical level signal with 10k
Ω
pull-up resistor.
