1. INTRODUCTION
1.1. Product Description
The GW7300-00 is a member of the Gateworks 7th generation Venice family of single
board computers targeted for small embedded applications such as IoT Gateways,
Machine Learning, Unmanned Aerial Vehicles (UAV) equipment, digital signage, and
robotics. The GW7300-00 features the 64-bit NXP™ i.MX8M Mini Quad Core ARM®
Cortex™-A53 SoC processor operating at 1.6GHz, 1GBytes of LPDDR4 DRAM, and
8GBytes of eMMC System Flash. Three Mini-PCIe expansion sockets can be used for
802.11ax/ac/b/g/n WiFi radios, 5G/4G/3G/CATM1 cellular modems and other PCI
Express peripherals. Peripheral headers support Digital I/O, Analog Input, RS232/485
and TTL Serial, I2C and SPI. A combined MIPI-DSI/CSI header with I2S audio offers
video input/output. A dual configuration connector supports both MicroSD & Nano SIM
simultaneously. A 3-Axis accelerometer is standard. An optional GPS and onboard Laird
Sterling 802.11b/g/n WiFi/Bluetooth module are available. The Gateworks System
Controller provides embedded features such as real time clock, voltage and
temperature monitor, serial EEPROM, programmable pushbutton switch, and advanced
power management with programmable board shut-down and wake-up for remote
sensor applications. A wide-range DC input power supply provides up to 15W of power
to the Mini-PCIe sockets for supporting the latest high-power radios. Power is applied
through a dedicated barrel jack or an Ethernet port in an active 802.3af/at or passive
Power over Ethernet (PoE) architecture. Ubuntu Linux BSP is supported.

ARMv8 Processor
The 64-bit NXP™ i.MX8M Mini Quad Core ARM® Cortex™-A53 SoC processor
includes many peripherals for supporting secure network and multimedia processing
and connectivity in small embedded applications.
● Quad Cortex-A53 processing cores
● Core operating frequency of 1.6GHz
● DDR4 SDRAM supports up to 2133MTps data rate
● Interfaces include Gigabit Ethernet, PCIe Gen2, and USB 2.0
● Peripheral interfaces include eMMC, SPI, I2C, UART, and GPIO
● Integrated acceleration for security
● Integrated 2D & 3D GPU (1x shader, OpenGL®ES 2.0)
● MIPI Display DSI & Camera CSI
● 1080p60 Encoder and Decoder
● IEEE1588 precision stamp protocol support
DDR4 SDRAM
The SDRAM resides in one LPDDR4 device soldered directly to the board. This
architecture supports DDR4 memory capacities from 1GByte to 4GBytes. The 32-bit
DDR4 interface operates at up to 1500MHz for supporting fast data transfer rates. The
factory default includes 1GByte of LPDDR4.
System Flash
The System Flash supports eMMC memory capacities from 4GBytes to 64GBytes. The
8-bit data bus interface supports double data transfer rates. The default boot device is
the eMMC Flash. The factory default is 8GBytes.
Mini-PCIe Sockets
Mini-PCIe is a small form factor PCI card that uses the same signal protocol, electrical
specifications, and configuration definitions as conventional PCI Express. The board
includes Gen 2 capable Mini-PCIe sockets with the following enhancements to the PCI
Express standard.
● The 3.3V power for the socket is increased from a maximum of 3.3W to 8W for
accommodating higher power radios. The 8W limit is due to the 0.5A limit of the
individual socket pins.
● The PCIe reset for the socket is unique and under software control.
● Certain sockets support both PCIe and USB 2.0 signaling
USB Support
● Slot J10 Supports PCIe, USB 2.0, SIM
● Slot J12 can support PCIe and USB 2.0.
● Slot J14 can support PCIe and USB 2.0.

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.
Micro-SD and Nano SIM Expansion
A combined Micro-SD and Nano SIM socket extends the functionality of the SBC.
The Micro-SD extends the local Flash storage capacity. The socket accepts small 11mm
by 15mm removable cards with storage capacities from 64Mbytes to 32Gbytes. The
4-bit data interface supports transfer rates up to 25Mbytes per second. This readily
available storage device is commonly used in cellular phones, GPS devices, portable
media players, and digital cameras.
The Micro-SD socket communicates with the processor using the SD[2] Secure Digital
interface and supports a card detect signal SD2_CD signal. Software drivers are
available for SD format cards.
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, J10, for cellular modem usage.
GbE Ethernet
The SBC supports a single Gigabit Ethernet port. The Ethernet port operates in a
10BASE-T, 100BASE-TX or 1000BASE-T configuration and includes 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 an 8-pin dual-row 2mm
header such as the JST B08B-PUDSS as an ordering option.
