board. Carrier drives low to force a
Module reset, floats the line otherwise.
Pulled up on Module. Driven by OD part
on Carrier.) S128 LVDS1+ (LVDS LCD data channel
differential pair)
P128 POWER_BTN# (Power-button input from
Carrier board. Carrier to float the line in
inactive state. Active low, level sensitive.
De-bounced on the Module Pulled up on
Module. Driven by OD part on Carrier.) S129 LVDS1- (LVDS LCD data channel differential
pair)
P129 SER0_TX (Asynchronous serial port data
out) S130 GND
P130 SER0_RX (Asynchronous serial port data
in) S131 LVDS2+ (LVDS LCD data channel
differential pair)
P131 SER0_RTS# (Request to Send
handshake line for SER0) S132 LVDS2- (LVDS LCD data channel differential
pair)
P132 SER0_CTS# (Clear to Send handshake
line for SER0) S133 LCD_VDD_EN (High enables panel VDD)
P133 GND S134 (LVDS LCD differential clock
pair)
P134 SER1_TX (Asynchronous serial port data
out) S135 LVDS_CK- (LVDS LCD differential clock
pair)

in) S142 Not connected
P142 GND S143 GND
P143 CAN0_TX (CAN0 Transmit output) S144 Not connected
P144 CAN0_RX (CAN0 Receive input) S145 WDT_TIME_OUT# (Watchdog Timer
Output)
P145 CAN1_TX (CAN1 Transmit output) S146 PCIE_WAKE (PCIe wake up interrupt to
host – common to PCIe; links A, B, C –
pulled up or terminated on Module)
P146 CAN1_RX (CAN1 Receive input) S147 VDD_RTC (Low current RTC circuit backup
power – 3.0V nominal. May be sourced from
a Carrier based Lithium cell or Super Cap.
See Section 7.3 RTC Voltage Rail of the
SMARC specification for an important
safety note on the implementation of lithium
backup batteries.)
