Huawei Lite OS is a discontinued lightweight real-time operating system (RTOS) developed by Huawei.[1] It is an open source, POSIX compliant operating system for Internet of things (IoT) devices, released under a three-clause BSD license.[2] Microcontrollers of different architectures such as ARM (M0/3/4/7, A7/17/53, ARM9/11), x86, and RISC-V are supported by the project. Huawei LiteOS is part of Huawei's '1+8+N' Internet of Things solution, and has been featured in a number of open source development kits and industry offerings.[3]

Smartwatches by Huawei and its former Honor brand run LiteOS.[4][5] LiteOS variants of kernels has since been incorporated into the IoT-oriented HarmonyOS with open source OpenHarmony.
