PCIe Socket Reset & WiFi Disable
The Mini-PCIe sockets support individual software programmable resets and shared
WiFi disable signals. The reset signal is controlled through the processor PCIe
interface and the WiFi disable signal is controlled through the Gateworks System
Controller.

Nano SIM Expansion

A Nano SIM socket extends the functionality of the SBC.
The Nano SIM (4FF) socket accepts 12.3 mm by 8.8 mm cellular SIM cards. The SIM
signals are routed to a single Mini-PCIe socket for cellular modem usage.

GbE Ethernet

The SBC supports Gigabit Ethernet. The Ethernet ports operate in a 10BASE-T,
100BASE-TX or 1000BASE-T configuration and include auto MDI/MDIX for
automatically switching data receive and data transmit pairs. Additional features include
full-duplex operation as well as support for auto- negotiation. The data interfaces
include direct-touch ESD protection that exceeds IEC61000-4-2-ESD. The Ethernet
MAC addresses are programmed into the Gateworks System Controller Configuration
EEPROM during automated factory testing.
The IEEE802.3 compliant Ethernet MAC Media Access Controllers are located in the
processor. The Gigabit Ethernet Port MAC communicates to an external PHY physical
layer device through an RGMII interface. The external PHY is reset under software
control using a processor digital I/O signal.
The RJ45 connector for the Gigabit Ethernet Port includes integrated status lights. The
green light is on for link and blinking for activity. The yellow status light indicates speed.
The yellow light is off for both 10Mbps and 100Mbps, and on for 1000Mbps.
The SBC input power can be provided through the Gigabit Ethernet Port jack in a
Passive Power over Ethernet architecture. This is discussed in greater detail at the end
of this section. The RJ45 connectors can be replaced with a header as an ordering
option.

USB Ports

The processor includes two USB ports. The default processor supports USB 2.0. Future
SOMs may support USB 3.0. One port is connected to a USB Type-C connector and the
other to a Mini-PCIe socket. The USB ports support low-speed 1.5Mbps transfers,
full-speed 12Mbps transfers, and high- speed 480Mbps transfers. The SBC is
configured as a Downstream Facing Port capable of sourcing 5V at 1.5A. The output
power is enabled through a CPU GPIO signal (GPIO[1]:DIO[12]) and the current fault
monitoring is monitored through another CPU GPIO signal (GPIO[1]:DIO[13]).
