AtomVM brings the BEAM programming model to tiny systems through a compact virtual machine built for constrained environments.

It runs standard BEAM bytecode and includes a carefully selected set of Erlang/OTP runtime APIs, plus original APIs tailored for microcontrollers and IoT devices.

With AtomVM, you can write your IoT applications in a functional programming language, using a modern actor-based concurrency model, making them vastly easier to write and understand!

AtomVM includes many advanced features, including process spawning, monitoring, message passing, pre-emptive scheduling, efficient garbage collection, Erlang Distribution, and JIT/AoT compilation.

It can also interface directly with peripherals and protocols supported on microcontrollers, such as GPIO, I2C, SPI, and UART. It also supports WiFi networking on devices that support it, such as the Espressif ESP32. All of this on a device that can cost as little as $2!
