[Back to the Top](https://github.com/mikeroyal/arduino-Guide/blob/main/README.md#table-of-contents)
[HeliOS](https://www.arduino.cc/reference/en/libraries/helios/) is an embedded operating system that is free for anyone to use. While called an operating system for simplicity, HeliOS is better described as a multitasking kernel for embedded systems.
[FreeRTOS](https://freertos.org/) is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors.
[Simba](https://simba-os.readthedocs.io/en/latest/getting-started.html) is a small OS for an Embedded Programming Platform like Arduino. It aims to make embedded programming easy and portable.
[Trampoline](https://github.com/TrampolineRTOS/) is a static RTOS for small embedded systems.
[DuinOS](https://github.com/DuinOS/DuinOS) is Framework (a wrapper) for use the FreeRTOSwith Arduino.
[VxWorks](https://www.windriver.com/products/vxworks) is an industry-leading real-time operating systems (RTOS) for building embedded devices and systems for more than 30 years.
[LynxOS](https://www.lynx.com/products/lynxos-posix-real-time-operating-system-rtos) is a native POSIX, hard real-time partitioning operating system developed by Lynx Software Technologies.
