What Is the Elastel EG324?
The Elastel EG324 is an ARM-based industrial computer designed as an IoT gateway for data acquisition, cloud integration and remote monitoring. According to Elastel's published specifications, it provides a high-performance embedded computing platform for industrial data acquisition and communication applications. Its interface set includes 4 x RS485/232 serial ports, dual 10/100 Mbps Ethernet ports, and a Mini PCIe socket that supports 4G LTE/3G/2G/NB-IoT/Cat M1 cellular modules as well as Wi-Fi modules. Elastel also offers related variants in the same family, including the EG324 Pro AIoT Gateway and the EG324 Lite IIoT Gateway.
Key Specifications and Technical Details
The defining characteristics of this class of device are its ARM architecture, its serial-heavy I/O layout and its expansion flexibility. The four configurable RS485/RS232 ports make it a natural fit for polling Modbus RTU devices such as energy meters, PLCs, sensors and VFDs, while the dual Ethernet ports allow one network segment to face the field devices and the other to connect upstream to a plant network or cloud broker. The Mini PCIe slot adds wide-area connectivity options without external dongles, and the fanless ARM design keeps power draw low and suits DIN-rail or cabinet mounting where dust and continuous operation are concerns.

Use Cases and Applications
Gateways of this type are commonly deployed in smart buildings, water and wastewater monitoring, solar and energy management, factory floor data collection and remote asset monitoring. A typical architecture uses the serial ports to collect Modbus or proprietary protocol data from field equipment, runs an edge application (often Node-RED, MQTT broker or a custom service) on the ARM CPU, and publishes the results over Ethernet or cellular to a cloud platform or SCADA historian. Because the device is ARM-based and fanless, it is well suited to unattended cabinets, rooftop enclosures and remote sites where maintenance visits are expensive.
Choosing Between an ARM Gateway and an x86 Industrial PC
ARM gateways excel at low-power, always-on protocol translation and telemetry. However, when an application needs to run Windows software, full desktop operating systems, heavier databases, local dashboards, vision workloads or multiple high-resolution displays, an x86 industrial PC is usually the better fit. The two categories are complementary: many installations use an ARM gateway at the edge for data collection and an x86 industrial computer at the cabinet or control room level for processing, HMI and storage. Buyers evaluating an EG324-class gateway should therefore confirm their software stack, operating system requirements and processing headroom before deciding on architecture.
Thinvent Products for Industrial Gateway and Edge Roles
Thinvent manufactures fanless industrial computers, mini PCs and all-in-one PCs built for continuous operation in demanding environments. For applications that need x86 compatibility, Windows 11 Pro, Ubuntu Linux or Thinvent's Thinux embedded Linux, the Thinvent IPC3 series pairs Intel Core i3-1215U processors (6 cores, up to 4.4 GHz, 10 MB cache) with up to 16 GB DDR4 RAM and 1 TB SSD storage, and is available with quad DB9 serial ports for Modbus and legacy device connectivity — a strong option where an ARM gateway's processing or OS support is not sufficient. Thinvent's range spans entry-level Celeron and Intel N-series mini PCs through to higher-performance industrial PCs, all designed for dust, heat and 24/7 duty in automation, kiosk, signage and edge computing deployments.
