The classic FreeRTOS distribution, a real-time operating system for microcontrollers and small microprocessors that submodules the FreeRTOS kernel and bundles libraries such as FreeRTOS+TCP, coreMQTT, and AWS IoT libraries. It supports 40+ processor architectures with a small memory footprint and MIT licensing.
Use cases
- run tasks on a microcontroller with a real-time kernel
- build IoT firmware that connects to AWS IoT via MQTT
- add a thread-safe TCP/IP stack with IPv6 to an embedded device
- perform over-the-air firmware updates on embedded devices
- port an RTOS to a new ARM Cortex-M microcontroller
- implement SMP multitasking on small processors
When to choose
- you need a proven, tiny-footprint RTOS with wide architecture support
- you are building connected embedded devices with cloud integration
- you want MIT-licensed, actively maintained embedded software with LTS releases
When to avoid
- you need a full-featured OS with filesystems and user processes on application processors
- your project targets Linux-capable hardware where a general-purpose OS fits better
- you need hard real-time certification guarantees beyond what the standard license provides
