Simplified Connectivity and Processing for Microsoft Azure Sphere 

IOTech’s Edge XRT for Azure Sphere provides edge solution for edge devices that utilize Azure Sphere-certified chips and Microsoft’s Azure Sphere OS. An Azure Sphere device is designed to integrate securely with the Azure Sphere Security Service running in the Cloud. The Security Service ensure the integrity of the device and provides the secure channel used by Microsoft to automatically download and install Azure Sphere OS updates and customer application updates to deployed devices.

Edge XRT provides two main capabilities for Azure Sphere devices:

  • Simplified, deployment-ready connectivity to IoT endpoints (sensors/devices/things) connected to Azure Sphere devices using a range of standard industrial protocols such as Modbus, BACnet and OPC UA and others. The ability to easily read IoT endpoint data and securely send it to its digital twin running on Azure IoT Hub. Via the digital twin commands can also be sent in the reverse direction to the IoT endpoint
  • An application platform for Azure Sphere Devices that allows users to create edge applications (edge processing/analytics/intelligence ) that can be downloaded and updated securely Over The Air (OTA) via the Azure Sphere Security Service throughout the life cycle of the device

Both of these capabilities significantly reduce development and integration costs for Azure Sphere systems. They help Azure Sphere users significantly speed time to market for new applications..


When deployed on Azure Sphere, Edge XRT currently supports the following OT protocols:







Please note that additional protocol support will be added over time. Please contact IOTech for the very latest availability.

Development Board

Edge XRT currently supports the following development boards:

Seeed MT3620 Dev Board

Avnet MT3620 Starter Kit

Guardian Modules

Guardian modules for retrofitting existing equipment

Guardian modules provide a quick path to securely connect existing equipment that either doesn’t support connectivity or doesn’t support it securely. A guardian module serves as an intermediary by physically attaching to the equipment via an existing peripheral and to the Internet via WiFi or Ethernet. The critical equipment itself is never exposed to the Internet. Guardian modules often come as complete hardware solutions

Edge XRT supports the following Guardian Devices:

  • Avnet Guardian 100 - attaches to and secures existing equipment via Ethernet or USB, and securely transfers data to and from the cloud over dual-band WiFi
