Explore the platforms and companies building on the RTOS.
Apache Software Foundation project
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'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 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.
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.
ArduSimple provides high-precision RTK GNSS solutions based on u-blox and Septentrio receivers, widely integrated with NuttX-based systems such as PX4. NuttX handles communication, control, and data processing while the GNSS module performs RTK positioning enabling centimeter-level accuracy for drones, autonomous vehicles, and surveying applications.
Japan Aviation Electronics Industry (JAE) develops flight controllers based on STM32H7 series microcontrollers running Apache NuttX via PX4 Autopilot. Their hardware is designed for high-reliability UAV and aerospace applications, with NuttX providing the real-time foundation for mission-critical avionics control.
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.
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 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 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.
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.
NXP provides broad hardware support for Apache NuttX across its MCU portfolio, including i.MX RT, LPC, and Kinetis series. NuttX runs on these platforms for real-time and industrial applications, with active community-driven board support and BSP contributions.
Seeed Studio actively supports Apache NuttX on its open hardware platforms such as XIAO and Wio series. With strong community collaboration, Seeed enables rapid prototyping and IoT development using NuttX in edge and embedded systems.
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 used NuttX in its ambitious modular phone project, an early effort to bring a hardware-modular smartphone to market.
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.
CU InSpace uses NuttX to run their rocket telemetry tracker, flown multiple times up to 30,000ft. NuttX is also used for all of the control logic for the InSpace hybrid rocket fill and ignition ground control systems, which is safety critical rocketry software.
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.
