IoT Gateway Solution Based on AM335X

Background Analysis

Industrial Internet of Things (IIoT) refers to IoT applications in industrial fields and represents the deep integration of industrial automation and information technology. Compared to general IoT, IIoT has stricter requirements, such as ultra-low latency, high reliability, and strong information security.

A typical IIoT architecture consists of four layers: perception, network, platform, and application. These layers are embodied in intelligent industrial devices, sensors, cloud platforms, smart control devices, gateways, and edge computing systems. Among these components, industrial IoT gateways and cloud platforms play foundational roles, closely tied to the characteristics of IIoT—such as performance, reliability, and information security requirements. Additionally, the gateway's unique topological position makes it ideal for integration with edge computing.

Pain Points Analysis:

Poor scalability—any new requirement necessitates a complete redesign of the circuit board.
Inconvenient remote maintenance.
Lack of support for the Linux operating system.

2. Solution Features

To address the challenges outlined above, Xinming proposes the XM-335X-GW development platform based on TI’s AM335x series processor, designed to meet evolving market demands. This platform adopts a core board + baseboard architecture. The XM-335X-GW core board integrates power management ICs, DDR3/DDR3L, eMMC/NAND Flash, EEPROM, and a 160-pin board-to-board signal expansion interface (80×2). The baseboard provides 12V power input, dual Gigabit Ethernet ports, one fiber optic port, LVDS, RGB LCD, a Mini PCI-E interface for 4G LTE, Wi-Fi and Bluetooth modules, USB HOST, RS485, RS232, and other peripheral interfaces.

1.1 Support for Multiple IoT Protocols Enables Seamless Cloud Connectivity

Designed specifically for gateway applications in the IIoT era, the XM-335X-GW development board supports various IoT protocols such as MQTT and TCP/IP. This simplifies and accelerates edge computing, ensures stable and reliable device connectivity, and enables smart devices to easily connect to the cloud.

1.2 Compact Size with Reliable Connectivity

The XM-335X-GW core board is powered by TI's AM335x series processor, delivering strong performance with a maximum clock speed of 1 GHz. It integrates onboard DDR3, flash/eMMC, EEPROM, and a PMIC power management chip. Designed with an 8-layer high-density, high-speed PCB and using a board-to-board connector (80-pin × 2) for signal expansion, the core board ensures stable and reliable connections while maintaining a compact footprint.

1.3 Rich Communication Interfaces + High-Performance HMI Display

The product supports high-speed communication interfaces including dual Gigabit Ethernet, one fiber optic port, Wi-Fi/Bluetooth, and 4G LTE. It also provides two display options: RGB LCD and LVDS. These features not only meet the high-speed communication requirements of gateway designs but also deliver excellent HMI display capabilities.
