5 Mbed OS

6 Platform OS principles Accelerate the development of IoT devices. Integrate all the necessary software components needed for constrained IoT devices (MCUs) Bring modern development methodologies and choice to MCUs to improve productivity Provide OS functionality and APIs across many vendor solutions to enable choice Accelerating the deployment of IoT devices. Provide standardised connectivity to the cloud across different transports Provide manageability from the cloud to open opportunities and reduce cost/risk Develop and leverage an ecosystem. Freely available and open source to remove barriers to entry and enable adoption In collaboration with partners to provide maximum gearing of investment for everyone The tools and web infrastructure to support an ecosystem and create network effects 6

7 Development model Mbed OS is an open source project developed by Arm, Partners, and a worldwide developer community. Building Mbed OS in collaboration allows: Increased effect of the effort put into it Increased overall developing power Increased reach and network effects Focus on individual core capabilities 7

8 Licensing Mbed OS is primarily open source, under Apache 2.0 or compatible licenses. Proprietary partner components (like radio drivers) can be under free binary license Partners pay a membership fee to support and contribute to project. Our partners share a vision for the future where development and deployment of commercial Internet of Things (IoT) devices is possible at scale, and a desire to collaborate on concrete plans and projects to make that vision a reality. Developers can use it for free. 8 partnership@mbed.com
