Arm Mbed OS is an open-source embedded operating system for IoT devices built on Arm Cortex-M microcontrollers, providing an RTOS, security foundations, connectivity, and drivers for sensors and I/O. Arm has announced end-of-life; the community fork Mbed CE is now the actively maintained continuation.

Use cases

• build a connected IoT product on an Arm Cortex-M microcontroller
• run an RTOS with sensor and I/O drivers on embedded hardware
• add security and cloud connectivity to an embedded device
• develop firmware for Mbed-compatible development boards
• port an embedded OS to custom microcontroller hardware

When to choose

• you are maintaining an existing Mbed OS project
• you want a mature, Apache-2.0 licensed embedded OS with built-in security and connectivity
• you are evaluating Mbed CE, the community fork, for new work

When to avoid

• you are starting a new project - Arm has sunset Mbed and no longer maintains it
• you need long-term vendor support or updated tooling
• your hardware is not Arm Cortex-M based
