Overview
The ReliaCOR 31-11 is a compact fanless and ventless embedded Edge AI system based on NVIDIA® Jetson Orin™ NX platform, developing up to 100 TOPS of AI performance.
Designed for industrial use cases, it offers reliable operation thanks to industrial grade ruggedization and a robust power supply. Very compact and power efficient, the ReliaCOR 31-11 can be deployed in dense installations.
The ReliaCOR 31-11 is powered by the NVIDIA® Jetson Orin™ NX platform featuring a 1024-core NVIDIA Ampere™ architecture GPU with 32 Tensor cores and an 8-core Arm® Cortex®-A78AE CPU, delivering up to 100 TOPS of AI performance. It supports rich I/O interfaces: 4x 1GbE with PoE , 4x USB 3.1 Gen 1 (5Gbps), two serial ports, 1x CAN interface and isolated Digital I/O. The ReliaCOR 31-11 features with a wide range of wireless connectivity capabilities: it can integrate as a factory option a LTE Cat 4 Global cellular modem with GNSS, Wi-Fi 6E and Bluetooth 5.3.
The ReliaCOR 31-11 offers best in class Cybersecurity: it leads the market with IEC 62443-4-1/-4-2 SL2. Protection starts at the hardware level, with full support for TPM 2.0, Secure Boot and an always-on physical antitampering monitor/logger that is active even when the system is removed from power. For most demanding customers, special production-only images can be configured with full hardware hardening (interface disabling) to further reduce the attack surface.
The ReliaCOR 31-11 comes with Everyware Software Framework (ESF), a commercial, enterprise-ready edition of Eclipse Kura, the open source Java/OSGi middleware for IoT Edge Gateways. Distributed and supported by Eurotech, ESF supports ready-to-use field protocols (including Modbus, OPC-UA, S7), MQTT connectivity, web-based visual data flow programming and deep configuration. ESF is also integrated with Everyware Cloud (EC) SaaS, Eurotech IoT Integration Platform, enabling advanced diagnostics, zero-touch provisioning, and full remote device access and management.

Setup Your AWS Account
Refer to the online AWS documentation at Set up your AWS Account. Follow the steps outlined in the sections below to create your account and a user and get started:
Pay special attention to the Notes.
Create Resources in AWS IoT
Refer to the online AWS documentation at Create AWS IoT Resources.
Follow the steps outlined in these sections to provision resources for your device:
Pay special attention to the Notes.
Install the AWS CLI
To install the AWS CLI on your host machine, refer to the instructions at Installing the AWS CLI v2. Installing the CLI is needed to complete the instructions in this guide.
Once you have installed AWS CLI, configure it as per the instructions in this online guide. Set the appropriate values for Access key ID, Secret access key, and AWS Region. You can set Output format to "json" if you prefer.
Alternatively, you can use the AWS CloudShell to send the same AWS CLI commands directly from your browser.
AWS IoT Core Connection
This section provides a guide on connecting an ESF device to the Amazon Web Services (AWS) IoT platform. This guide covers the usage of the ESF Cloud Connector for AWS IoT Core and other integrations with AWS IoT services like AWS Greengrass.
Prerequisites
In order to connect a device to AWS IoT Core, the following prerequisites are needed:
- An AWS IoT account
- A device with ESF version 3.3 or greater installed
Provision the Device with credentials
AWS IoT Core supports three types of provisioning:
- Single Thing Provisioning
- Just In Time Provisioning (JITP)
- Bulk Provisioning
You can find detailed instructions on Single Thing Provisioning in the ESF documentation website, here. JITP, Just In Time Registration and Bulk Provisioning require custom setup, usually involving a discussion with one of our Solution Architects. Please feel free to contact us if you need to enable JITP, JITR or Zero-Touch Provisioning on your Eurotech device.
Connectors Available
Two alternative ways can be used to connect to AWS IoT Core from ESF:
- Using the ESF Cloud Connector for AWS IoT Core (Requires ESF 6.1.0+)
- Configuring the Generic ESF MQTT Connector (Requires ESF 3.3.0+)
Both ESF Connectors support all three provisioning techniques.
Completing device provisioning is a prerequisite before an IoT device can successfully connect to AWS IoT Core.
Running the demo
ESF Wires can be leveraged to create a simple demo flow to test the connection to AWS IoT Core.
- Open the ESF Web Console, by accessing ESF from your browser.
- Login with your credentials (default credentials can be found in the ESF documentation)
- Navigate to the Cloud Connections section of ESF
Once your Eurotech device is connected to IoT Core, the relevant ESF Cloud Connector will look as follows: 
- Click on "New Pub/Sub" and select a new AwsThingPublisher from the list. Assign it a name (e.g. demo.publisher)
A new Thing Publisher will be associated to this Cloud Connection. Select the newly created publisher and configure it with a unique topic (e.g. demo.topic) 
- Navigate to the Wires section
- Add to the Canvas a Timer component and a Publisher component
- Link the components together
- Configure the Publisher component to link to the previously created AWSThingPublisher
- Apply the changes
Verify messages in AWS IoT Core
AWS IoT Core will receive periodic timer events directly from the ESF Wire Graph.
- Go to IoT Core in the AWS Console
- Activate the MQTT test client
- subscribe to the topic configured in the AWSThingPublisher (e.g. demo.topic)
Debugging
The Eurotech device default development configuration is meant to ease access and debugging.
- Ethernet Port LAN1 (7) is configured as DCHP Server with a IPv4 address of 172.16.0.1.
- Ethernet Port LAN2 (7) is configured as DHCP Client.
SSH protocol is enabled on standard port TCP 22 with, with guest user access. Password is the serial number of the unit, which you can find on the product label. To access the system, run:
You can use the eth_journalctl command to access the aggregated logs of the system:
