Corstone SSE-050 reference design 

The Corstone SSE-050 reference design is a subsystem for an entry-level system that allows designers to get the foundation of IoT or embedded systems quickly. The Corstone SSE-050 reference design is ready to run Mbed OS out-of-the-box. See the following SSE-050 reference design:

Based around the Arm Cortex-M3 processor, the subsystem is ready to connect your external peripherals to design your custom solution. It is modifiable, so that you can tune it to your needs without having to build your system from the ground up.

To improve performance, reduce power and improve integration, you can choose to connect it to an embedded flash. You also have the option of connecting the code interface in any other way, even integrating the subsystem as part of a larger system.

Similarly, its expansion ports allow you to have a very high level of flexibility, making the Corstone SSE-050 a great start for your next SoC.
