Robustel EG3210 Gateway

Overview

The EG3120e is an Industrial Edge Computing Gateway with LTE, eSIM and Multi-Serial Integration, built to connect legacy OT equipment to modern monitoring infrastructure.

Powered by a quad-core ARM Cortex-A53 processor at 2.0 GHz, 2 GB LPDDR4 RAM, and 8 GB eMMC storage, the EG3120e is designed for applications that need more than simple connectivity. It can run local workloads, protocol conversion, data collection, and buffering closer to industrial equipment, reducing reliance on external PCs or separate serial concentrators.

Built on RobustOS Pro, based on Debian 11, the EG3120e gives developers access to familiar Linux tools, standard programming languages, APT/DPKG package management, and a broader software ecosystem for building and deploying edge applications.

For OT integration, the EG3120e supports up to 4 × RS-485, 1 × RS-232, 4 × DI, 4 × DO, 2 × AI, and 1 × CAN, making it well suited to industrial environments with meters, inverters, machinery, controllers, sensors, and legacy field devices.

Key Features

Edge Computing — Quad-core ARM Cortex-A53 @ 2.0 GHz with up to 2 GB RAM and 8 GB eMMC for local applications, data processing, and edge workloads.
RobustOS Pro — Debian 11-based operating system with support for C, C++, Python, Java, Node.js, APT, DPKG, and custom application development.
Multi-Serial — Up to 4 × RS-485, 1 × RS-232, 4 × DI, 4 × DO, 2 × AI, and 1 × CAN for connecting industrial equipment and legacy field devices.
eSIM/eUICC Support — Remotely provision and deploy up to 8 eSIM/eUICC profiles.
Industrial Design — Metal enclosure, IP30 protection, TPM 2.0, watchdog, RTC, microSD support, DIN-rail or wall mounting, and -25 °C to +70 °C operating temperature.

Connectivity

LTE Cat 4, 1 × Mini SIM, 1 × MFF2 eSIM with SGP.22 profile download and removal, 2 × Ethernet, and Wi-Fi 6 — a flexible platform for connecting equipment locally while maintaining remote access, monitoring, and cellular lifecycle control.

Example Use Cases

Solar & Distributed Energy

Connect solar, EV charging, and distributed energy assets through one compact edge gateway. The EG3120e supports up to 4 × RS-485, 2 × AI, 4 × DI, 4 × DO, CAN, LTE Cat 4, and eSIM/eUICC, allowing operators to collect field data, run local edge logic, and manage connectivity across remote energy sites.

Industrial Data Acquisition

Modernise existing production environments without replacing working machinery. The EG3120e connects serial devices, sensors, controllers, and industrial equipment using RS-485, RS-232, DI/DO, AI, CAN, Ethernet, and Wi-Fi 6, while RobustOS Pro provides a Debian-based environment for local data processing and custom edge applications.

OEM Machinery Service

Add remote service, telemetry, and edge application capability to industrial machinery. The EG3120e combines LTE Cat 4, eSIM/eUICC, Wi-Fi 6, Ethernet, RS-485, RS-232, DI/DO, AI, CAN, and Debian-based RobustOS Pro, helping OEMs connect equipment, collect machine data, and support products after deployment.
