    Why RT-Thread?

    Rich Components

    Device virtual file system
    Supports FAT, UFFS, NFSv3, ROMFS, RAMFS, etc.
    Device management framework
    Uses a unified interface to access the hardware peripherals.
    Low power management framework
    The system can go to sleep mode automatically, and supports dynamic voltage and frequency scaling.
    Hardware encryption &decryption framework
    Supports algorithms such as hash, symmetric, gcm, etc.
    Protocol stack
    Supports Ethernet, Wi-Fi, Bluetooth, NB-IoT, 2G | 3G | 4G, Http, MQTT, and LwM2M, etc.
    Remote upgrade FOTA
    Safe and reliable, and which supports encryption, anti-tampering, breakpoint resume, intelligent restoration, backtracking and other mechanisms.
    Dynamic modules
    The dynamic modules and the kernel can be compiled separately, and at runtime, the compiled dynamic modules are loaded into the kernel to run.
    Third-party components
    Support Yaffs2, Sqlite, FreeModbus, Canopen, etc.

    Great Portability & Software Ecology

    Supports mainstream chip architecture
    Such as ARM Cortex-M, MIPS, X86, Xtensa, C-Sky, RISC-V, ARC, etc.
    Unified interface specification
    Various MCUs and their peripheral interfaces are highly abstracted and the programming interfaces are unified.
    POSIX interface
    Easy to port Linux or Unix programs to RT-Thread. Support for File I/O, Signals, PThreads, IPC, etc.
    Seamless application migration
    Follows highly reusable software design principles, one-time programming, permanent use.
    Multiple compiling tools
    Such as Keil, IAR, GCC, Eclipse, Visual Studio and RT-Thread Studio development environment, etc.
    Rich BSPs and porting templates
    Lots of BSPs as well as porting templates that can be quickly ported to the target chip based on the porting template.

    Tiny & Elegant

    Small in Size
    RT-Thread has a Nano version with a very small size and refined hard real-time kernel, which requires only 3KB of ROM and 1.2 KB of RAM.
    Feature-rich
    RT-Thread has rich features, such as, hard real-time scheduler, thread management, interthread synchronization and communication, clock management, interrupt management, memory management, etc.

    RT-Thread Studio

    RT-Thread studio is one-stop development tool, it has easy-to-use graphical configuration system and a wealth of software packages and components resources, which makes IoT development simple and efficient.

    • Community version is free forever.
