Mbed OS is an open-source, device software platform for the Internet of Things. Contributions are an important part of the platform, and our goal is to make it as simple as possible to become a contributor.
|
||||
|
||||
To encourage productive collaboration, as well as robust, consistent and maintainable code, we have a set of guidelines for contributing to Mbed OS. Please see: [contributing guidelines](https://os.mbed.com/docs/latest/reference/contributing.html).

Arm Mbed OS is an open source embedded operating system designed specifically for the "things" in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices.
|
||||
|
||||
Mbed OS provides a platform that includes:
|
||||
* Security foundations.
|
||||
* Cloud management services.
|
||||
* Drivers for sensors, I/O devices and connectivity.
