FreeRTOS™
Real-time operating system for microcontrollers
Developed in partnership with the world’s leading chip companies over an 18-year period, and now downloaded every 170 seconds, FreeRTOS is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors. Distributed freely under the MIT open source license, FreeRTOS includes a kernel and a growing set of IoT libraries suitable for use across all industry sectors. FreeRTOS is built with an emphasis on reliability and ease of use.
Why FreeRTOS?
Trusted kernel
With proven robustness, tiny footprint, and wide device support, the FreeRTOS kernel is trusted by world-leading companies as the de facto standard for microcontrollers and small microprocessors.
Accelerate time to market
With detailed pre-configured demos and Internet of Things (IoT) reference integrations, there is no need to determine how to setup a project. Quickly download, compile, and get to market faster.
Broad ecosystem support
Our partner ecosystem provides a breadth of options including community contributions, professional support, as well as integrated IDE and productivity tools. Predictability of long term support
FreeRTOS offers feature stability with long term support (LTS) releases. FreeRTOS LTS libraries come with security updates and critical bug fixes for two years. Maintained by AWS for the benefit of the FreeRTOS community.
Features
Tiny, power-saving kernel
Scalable size, with usable program memory footprint as low as 9KB. Some architectures include a tick-less power saving mode
Support for 40+ architectures
One code base for 40+ MCU architectures and 15+ toolchains, including the latest RISC-V and ARMv8-M (Arm Cortex-M33) microcontrollers
Modular libraries
A growing number of add-on libraries used across all industry sectors, including secure local or cloud connectivity
AWS Reference Integrations
Take advantage of tested examples that include all the libraries essential to securely connect to the cloud
