Documentation and source code
Microsoft publishes free Azure RTOS documentation including how-to guides, source code, tutorials, and API reference documentation.
Our industry hardware partners have designed solutions with Azure RTOS fully licensed. No additional licensing when using Azure RTOS licensed hardware.
Annual licensing program
For hardware not licensed as Azure RTOS licensed hardware, Microsoft offers a simple annual licensing program for all other devices and components.
The full source code for all Azure RTOS components is available on GitHub. You may freely explore, develop, test, and adapt Azure RTOS to suit your pre-production needs. A license is required to distribute or sell components and devices unless using Azure RTOS licensed hardware.
Visit GitHub to learn more
It depends. If you deploy to any of the pre-licensed devices that are listed at GitHub the production license is automatically included, and you do not need to pay for any additional licensing. If you prefer to deploy to any other device, you must purchase a license from Microsoft.
All 8 components are included in the license:
- Azure RTOS ThreadX
- Azure RTOS NetX
- Azure RTOS NetX Duo
- Azure RTOS FileX
- Azure RTOS GUIX
- Azure RTOS GUIX Studio
- Azure RTOS USBX
- Azure RTOS TraceX
Access to all Azure RTOS certification artifacts is available for $30K USD per year subscription. Contact us by completing our IP Licensing Programs form for additional questions or to purchase a subscription.
Azure Sphere customers are eligible to use Azure RTOS in Azure Sphere production deployment for free. This only applies to customers using the MT3620 MCU-based Azure Sphere offering. Any use of Azure RTOS outside of Azure Sphere still requires licensed hardware or a license from Microsoft.
