We are thrilled to announce the release of AtomVM v0.7.0-alpha.0, the first pre-release on the road to v0.7.0 and by far the biggest AtomVM release to date. This alpha includes over two year of development work and introduces several groundbreaking features, including distributed Erlang, JIT compilation, big integer support, a comprehensive crypto module, and ETS.
As an alpha release, some APIs may still evolve before a final release. For production deployments requiring maximum stability, we recommend staying on the v0.6.x release branch. We encourage everyone to try this alpha and report any issues, your feedback is invaluable.
OTP-28 and OTP-29 are now supported. This is a major improvement over v0.6.6, which did not include OTP-28 support. On macOS, both Homebrew and MacPorts default to OTP-28 or later, so this release works out of the box with default system installations. You can use asdf or mise to manage multiple Erlang/OTP versions if needed.
AtomVM now supports the Erlang distribution protocol. AtomVM nodes running on microcontrollers can connect to standard BEAM nodes or other AtomVM instances, enabling use cases such as debugging an MCU from an OTP shell, coordinating multiple microcontrollers, or building mixed clusters. The release includes a pure Erlang erl_epmd client, support for external pids, ports, and refs, remote shell capabilities, and cookie-based authentication. The distribution protocol also supports alternative transport carriers beyond TCP/IP (e.g. SPI, I2C).
AtomVM now supports four execution strategies: emulated (bytecode interpretation, the default), JIT (runtime native compilation), native ahead-of-time compilation, and a hybrid mode. The JIT compiler is itself written in Erlang, with supported architectures including RISC-V32, ARM v6-M, x86_64, and aarch64.
Integer support has been extended to 256-bit (sign + 256-bit magnitude), with all arithmetic and bitwise operations working on big integers. Pattern matching and serialization via binary_to_term and term_to_binary is also supported.
A comprehensive crypto module has been added, including key generation and exchange, digital signatures, streaming hashes and MACs, AEAD encryption, PBKDF2 key derivation, and Ed25519 support via optional libsodium integration.
A limited but functional implementation of the OTP ets interface is now available, including support for set, bag, and duplicate_bag table types.
This release adds initial support for ESP32C5 and ESP32C61, WiFi for ESP32P4 (via esp-wifi-external), and 10 new STM32 families enabled by switching to the official ST HAL/LL SDK. ESP32 release images are now built with ESP-IDF v5.5.
Native GenServer and Supervisor support, Function.ex and Protocol.ex for Elixir 1.18, and a new -DATOMVM_ELIXIR_SUPPORT=on cmake flag for ESP32 builds.
If upgrading from v0.6.x, please review the UPDATING.md file. Notable breaking changes include the new init:boot/1 entry point, ports replacing pids for native processes, bsl overflow checking, and the renamed C API external_term module.
Pre-built binaries for ESP32 (13 chip variants, standard and Elixir flavors), Raspberry Pi Pico (pico, pico_w, pico2, pico2_w), and WebAssembly (Node.js and browser) are available on the GitHub releases page. Users who need custom builds or STM32 support should consult the Build Instructions.
The complete Getting Started Guide and full Changelog are available in the documentation.
This release would not have been possible without our contributors. We also want to extend a special thank you to Dashbit and Software Mansion for having supported the development of AtomVM. Thank you!

]]>This weekend, the Elixir community piyopiyo.ex will host an in-person AtomVM introductory session in Nagoya.
The event, AtomVM Intro, with a Visit to Toyokuni Jinja, is structured as a practical entry point for developers who want to get started with AtomVM and embedded Elixir.
The session is designed to introduce participants to AtomVM in a hands-on setting. According to the published agenda, the program includes an overview of AtomVM together with guided setup work.
That makes the event a useful starting point for developers who are interested in understanding how AtomVM fits into embedded and IoT development.
Beyond the introduction, the event also includes creating an AtomVM project.
This is an important part of the format: it moves quickly from concepts to a working development environment and an initial project structure, giving participants a concrete way to begin experimenting with AtomVM on their own.
For AtomVM, events like this help lower the barrier to entry for developers exploring Elixir beyond traditional server and web applications.
As more local communities begin to include embedded topics in their learning activities, AtomVM continues to become part of the practical toolkit for running BEAM languages in constrained environments.
This is a local meetup, but it reflects a broader pattern: interest in embedded Elixir continues to grow, and AtomVM is increasingly part of that conversation.
We look forward to seeing how sessions like this help more developers take their first steps with AtomVM.
]]>This January, something exciting is happening in Japan.
Davide Bettio, the creator of AtomVM, will visit the country and spend time with the Elixir beginner community piyopiyo.ex in an in-person technical exchange (Davide BettioさんとAtomVMを囲む会).
His visit highlights a growing interest in using Elixir and AtomVM for embedded and IoT development in the region.
piyopiyo.ex is a beginner-friendly community. While many members come from web development backgrounds, recent activities have shifted toward hardware, exploring embedded Elixir using both Nerves and AtomVM.
Nagoya was chosen for its strong ties to manufacturing and hardware engineering. It’s also geographically well-positioned, making it a natural meeting point for developers from across Japan.
As part of its AtomVM work, piyopiyo.ex maintains the Piyopiyo PCB—an open-source ESP32-S3 board designed to make embedded Elixir approachable. The board and its documentation are actively developed and maintained by community members.
This visit is supported by Seeed K.K. Japan, with special thanks to MATSUOKA Takashi for generously providing the venue and for long-standing support of IoT communities in Japan.
While this is a local meetup, it reflects a broader trend: more developers are discovering how AtomVM enables Elixir in constrained environments.
We look forward to sharing what we learn with the wider AtomVM community.
この1月、日本でちょっと嬉しい出来事があります。
AtomVM の作者である Davide Bettio さんが来日し、Elixir 初心者向けコミュニティ piyopiyo.ex と対面で技術交流を行います（Davide BettioさんとAtomVMを囲む会）。
今回の来日は、この地域で Elixir と AtomVM を組み込み・IoT 開発に活用しようという関心が高まっていることを示しています。
piyopiyo.ex は初心者向けのコミュニティです。Web 開発の経験者が多い一方で、最近はハードウェア寄りの取り組みにも軸足を移し、Nerves と AtomVM の両方を使った「組み込み Elixir」を模索しています。
名古屋は、ものづくりやハードウェア開発との結びつきが強い地域です。地理的にもバランスが良く、日本各地の開発者が集まりやすい自然な合流点でもあります。
piyopiyo.ex では AtomVM の取り組みの一環として、Piyopiyo PCB を整備しています。これは、組み込み Elixir を取り組みやすくするために設計された、ESP32-S3 ベースのオープンソース基板です。基板本体とドキュメントは、コミュニティメンバーが継続的に開発・保守しています。
今回の場は Seeed K.K. Japan にご支援いただいています。会場をご提供いただいたこと、そして日本の IoT コミュニティへの長年のご支援に対し、MATSUOKA Takashi さんに特別な感謝を申し上げます。
これはローカルな集まりではありますが、より大きな流れを映しています。制約のある環境でも Elixir を動かせる AtomVM によって、できることの幅が広がると感じる開発者が増えています。
今回得られた学びは、AtomVM コミュニティ全体へ共有していきます。
]]>We’re excited to announce that AtomVM will be featured in two compelling talks at CodeBEAM Berlin 2025 next week! Join us to learn about the latest developments in running BEAM languages on microcontrollers and beyond.
November 5th, 2025
Paul Guyot will present how just-in-time compilation is being brought to AtomVM, the virtual machine for microcontrollers. He’ll compare AtomVM’s approach with the BEAM’s BeamASM, focusing on the unique challenges of compiling on devices with as little as 128 KB of RAM and maintaining portability across multiple architectures (RISCV, ARM32, Xtensa, WASM). The talk will also reveal how LLMs are helping tackle this complex engineering challenge.
November 6th, 2025
Davide Bettio will demonstrate running Erlang, Elixir, and Gleam on palm-sized devices, showcasing AtomVM’s unique position in the embedded BEAM ecosystem. With practical examples in all three languages, he’ll explore IoT applications and beyond, including WebAssembly support and running BEAM languages directly in browsers. The session will provide actionable insights for building small-footprint applications across diverse environments.

]]>We are excited to announce the release of AtomVM v0.6.6!
First, a quick note for users of OTP-28: Unfortunately, this release does not yet include support for OTP-28. We recommend using a supported version such as OTP-27 for the best experience with AtomVM v0.6.6.
That said, if you’re eager to experiment, our main development branch includes support for OTP-28. We strive to keep up with the latest OTP changes, so adventurous users are welcome to try it out—with the usual caution that comes with using a development branch.
If you’re on macOS, be aware that both Homebrew and MacPorts now default to OTP-28. To install an earlier version, you can use:
brew install erlang@27
Alternatively, consider using asdf or mise to manage multiple Erlang/OTP versions with ease.
Also note: since MacPorts has already moved to OTP-28, AtomVM v0.6.6 will not be available on MacPorts.
This release includes a vast number of changes and improvmenets, for the full set of bug fixes, changes and additions consult the Changelog.
Download images and binaries are available for most platforms, except STM32, are available from
AtomVM Releases on GitHub. STM32 users as
well as anyone needing to build a generic_unix port for a device without release binaries should
consult the Build Instructions. MacOS
users also have the option of
installing with macports.
The git repository and tarballs of the AtomVM source release for all platforms can be found on our GitHub AtomVM page.
Documentation for the v0.6.6 release of the AtomVM virtual machine, including a Getting Started Guide, can be found in the AtomVM Documentation.
As always, tools, drivers, and modules are available on the GitHub AtomVM Project page.
This release wouldn’t be here without the awesome work of our contributors: Davide Bettio, Paul Guyot, Winford, Peter M, and everyone else who contributed.
Many thanks to as well to the bug reporters who have helped make this release possible.
