## What it is
Discovery is an open-source book from the Rust Embedded working group that teaches microcontroller programming through Rust, with versions targeting the micro:bit v2, micro:bit v1, and STM32F3 discovery boards. It combines tutorial documentation with hands-on example code licensed under CC-BY 4.0 and Apache-2.0/MIT.

## Use cases
- learn embedded programming with Rust from scratch
- get started with microcontrollers using a micro:bit v2
- find a beginner tutorial for Rust on STM32 boards
- work through hands-on embedded Rust examples
- teach a workshop on Rust and microcontrollers
- understand no_std Rust development on hardware

## When to choose
- you are new to embedded systems and want a guided Rust introduction
- you own a micro:bit v2, micro:bit v1, or STM32F3 discovery board
- you prefer learning through a structured book with runnable examples

## When to avoid
- you need production embedded Rust guidance rather than a beginner tutorial
- you target Espressif or other boards not covered by the book
- you already know embedded Rust and only need API reference material

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, embedded, developer-tools
- domain: embedded-systems, tutorials, education, programming-languages
- platform: embedded, cross-platform, rust
- tags: embedded-rust, microcontrollers, microbit, stm32, book, rust-embedded
