Ariel OS is a library operating system for secure, memory-safe, low-power Internet of Things, written in #RustLang.
We have published our first releases, but are constantly working toward more featurer, following our vision. Stay tuned.

With today's release of 0.4.0 of Ariel OS, an operating system for portable embedded Rust, our BLE API now also supports the ESP32 platform. We've enhanced the integration of Clippy by using Rust 1.94's configuration includes, and enhanced lifetimes on our I2C abstraction.

After about 2 years of planning, our take on letting kids choose their own music is running. Like the popular Tonies / TonUINO boxes, users can place magnetic NFC tags on top of a small device to start playback. But this device has no built-in speaker. Instead, it connects to a media PC via Bluetooth, and starts the right song or playlist.
Materials include ready-made microcontroller boards, simple hand-soldered connectors, laser-cut case, and software based on @ariel.
In my lunch break i had the chance to try out ArielOS, which is a collection/framework to build and deploy firmware for microcontrollers in Rust.
It abstracts some of the boring repetitive work away from the user, for example board switches are really easy, so you can write your code board-agnostic (to a certain extent).
Really cool.
We are delighted to announce Ariel OS v0.3.0, featuring support for BLE, a sensor abstraction, and many other new features and updates.
… and our BoF slot at #FOSEM was scheduled for Saturday 11:00 (at UA4.222).

Ariel OS – A Rust RTOS for IoT microcontrollers
Ariel OS is a new RTOS for microcontrollers written in Rust with support for popular hardware architectures (Arm Cortex-M, ESP32, RISC-V) and boards from Espressif, Nordic Semi, Raspberry Pi, and STMicroelectronics. Ariel OS is built on top of Embassy Rust framework and embedded-hal Hardware Abstraction Layer (HAL) for embedded systems, and adds several OS functionalities and a multi-core capable scheduler.

Ariel OS is a new RTOS for microcontrollers written in Rust with support for popular hardware architectures (Arm Cortex-M, ESP32, RISC-V) and boards from Espressif, Nordic Semi, Raspberry Pi, and STMicroelectronics. Ariel OS is built on top of Embassy Rust framework and embedded-hal Hardware Abstraction Layer (HAL) for embedded systems, and adds several OS functionalities and a multi-core capable scheduler. It is mainly designed for secure, memory-safe, networked applications on microcontrollers. The developers further describe Ariel OS as follows on the project's website: Ariel OS follows an approach whereby it simultaneously integrates a curated ecosystem of libraries (available via crates.io), and adds missing operating system functionalities as depicted below. Such functionalities include a preemptive multicore scheduler, portable peripheral APIs, additional network security facilities, as well as a meta-build system to bind it all together. As a result, a low-power IoT developer can focus on business logic sitting on top of
We are going to #FOSDEM!
Meet us at our presentation on Sunday 10:00 (room UD2.120) https://fosdem.org/2026/schedule/event/BGPKAM-ariel-os-embedded-rtos/, possibly at a BoF on Saturday (we'll announce details when confirmed), or roaming around the event.
To get in touch, follow the sounds of people talking about #embedded #RustLang, DM us, or ping us on Matrix https://app.element.io/#/room/#ariel-os:matrix.org.
