## What it is
A Rust Hardware Abstraction Layer (HAL) implementing embedded-hal traits for AVR microcontrollers and common boards like Arduino. It provides board-level crates (arduino-hal, atmega-hal, attiny-hal) built on avr-device for writing embedded firmware in Rust.

## Use cases
- write Rust firmware for Arduino Uno
- blink an LED on an ATmega microcontroller
- program AVR chips with embedded-hal traits
- set up a Rust embedded project for Arduino boards
- flash Rust programs to AVR hardware with cargo
- use Rust instead of C++ for Arduino development

## When to choose
- you want to write Rust code for AVR microcontrollers or Arduino boards
- you need embedded-hal compatible drivers for ATmega or ATtiny chips
- you prefer cargo-based build and flash workflow via ravedude

## When to avoid
- you target ARM Cortex-M or other non-AVR microcontrollers
- you need stable Rust toolchain support (nightly is required)
- you want a batteries-included Arduino IDE experience with libraries and shields

## Facets
- artifact type: library
- maturity: active
- function: embedded, sdk, developer-tools
- domain: embedded-systems, hardware, programming-languages
- platform: embedded, rust, cross-platform
- tags: avr, arduino, embedded-hal, rust, microcontroller, no-std, hardware-abstraction-layer
