Market Share & Ecosystem
Apache NuttX powers devices across aerospace, consumer electronics, IoT, and industrial systems. Explore the platforms and companies building on the RTOS.
Apache Software Foundation project
Consumer Electronics & Wearables
High-volume audio, wearables, and large-scale consumer ecosystems.
Sony Audio Devices & Spresense
Sony uses NuttX in its audio players and embedded ecosystem. The Sony Spresense platform (including multiple boards and modules) runs NuttX as its primary operating system, enabling high-performance audio and edge AI sensing.
Google / Fitbit Smartwatches
Google's Fitbit ecosystem uses NuttX in its smartwatch platforms. Their engineers have presented multiple talks at NuttX International Workshops, demonstrating active, ongoing involvement in the RTOS community.
Xiaomi / OpenVela
Xiaomi has one of the largest NuttX deployments in the world. Over 1,000 SKUs are reported to run NuttX, spanning smartwatches, smart speakers, displays, and EV-related systems, all under the OpenVela platform umbrella.
Drones, Robotics, and Automotive
Mission-critical mobility, flight control, and automotive ECUs.
PX4 Ecosystem
Every drone built using PX4 Autopilot runs Apache NuttX. This includes aircraft manufactured by Auterion, 3DR, XMobots, and many others. NuttX handles the real-time flight control demands where determinism is non-negotiable.
Li Auto (Electric Vehicles)
Li Auto integrates NuttX in its Electronic Control Units (ECUs). Both Li Auto and Xiaomi have actively worked toward certifying NuttX for automotive use, demonstrating its readiness for safety-critical embedded systems.
IoT, Embedded, and OS Integrations
Connected platforms, robust APIs, and SIL0 industrial controls.
Samsung TizenRT
Samsung uses NuttX as the underlying kernel for TizenRT, their IoT operating system deployed heavily across connected and embedded devices in their product lineup.
Espressif ESP32 Family
Espressif Systems actively contributes to the NuttX mainline. The full ESP32 family (including S2, S3, H2, and P4 variants) has first-class support, making it one of the most widely deployed platforms for IoT products using NuttX.
Elektroline
Elektroline deploys NuttX in tram track systems (BRCg2, VTK25) and remotely controlled disconnectors. NuttX provides interconnection over CAN, USB, and Ethernet, GUI via LVGL, and data logging to SD card or NOR flash memory at SIL0 safety level.
Meadow by Wilderness Labs
Wilderness Labs uses NuttX in its Meadow platform. Because NuttX is POSIX-compliant and Unix-like, it enables easier portability of Linux-based .NET applications to microcontrollers, bridging the gap between desktop development and embedded hardware.
Aerospace, Space, and Historical Uses
Mission-critical boundaries and notable technology projects.
Japanese Lunar Mission (2024)
NuttX powered a robotic system aboard the Japanese lunar exploration mission in 2024, highlighting the RTOS's reliability in extreme environments where failure is not an option.
Google Modular Phone
Google used NuttX in its ambitious modular phone project, an early effort to bring a hardware-modular smartphone to market.
Motorola Moto Mods
Motorola deployed NuttX in Moto Z smart accessories (Moto Mods), enabling modular hardware extensions such as cameras, projectors, and speakers to communicate intelligently with the host device.
Robotics Frameworks
Foundational contributions to the open-source robotics ecosystem.
micro-ROS
The widely adopted micro-ROS robotics framework was initially developed directly on NuttX before expanding to support other RTOS platforms, cementing NuttX's role as the foundational platform for bringing ROS 2 to microcontrollers.
