## What it is
Arduino IDE hardware support files that enable programming STM32-based boards (especially STM32F103 and LeafLabs Maple/Maple Mini) with the Arduino IDE 1.8.x. It is based on LibMaple and provides board definitions, cores, and toolchain integration for generic STM32F103 development boards.

## Use cases
- program STM32F103 blue pill boards with Arduino IDE
- use Maple mini with Arduino sketches
- flash Arduino code to cheap STM32 Cortex-M3 boards
- set up Arduino hardware files for generic STM32 boards
- use 72MHz ARM Cortex-M3 as an Arduino-compatible microcontroller

## When to choose
- you have an STM32F103 board like the Blue Pill or Maple Mini and want Arduino IDE support
- you want a lightweight, fast alternative to AVR Arduino boards
- you are following STM32duino community tutorials for F1 boards

## When to avoid
- you use newer STM32 chips (F4, H7, etc.) - the official STM32duino core is better supported
- you need production-grade, safety-critical firmware - the project is explicitly experimental
- you use Arduino IDE 2.x exclusively, as this targets IDE 1.8.x
