## What it is
The official Arduino core that enables Arduino programming for the ESP32 family of SoCs, built on top of ESP-IDF. It provides board definitions, libraries, and toolchain integration so sketches can be compiled and flashed to ESP32 chips from the Arduino IDE or CLI.

## Use cases
- program ESP32 boards with Arduino sketches
- build IoT devices using ESP32 and Arduino libraries
- use WiFi and Bluetooth on ESP32 from Arduino code
- flash firmware to ESP32, ESP32-S3, or ESP32-C3 boards
- prototype embedded projects with the Arduino ecosystem

## When to choose
- you want the familiar Arduino API on ESP32 hardware
- you need quick prototyping for IoT or embedded projects
- you rely on the large ecosystem of Arduino libraries

## When to avoid
- you need fine-grained control or full ESP-IDF features
- you target non-ESP32 microcontrollers
- you require hard real-time guarantees beyond what Arduino abstractions provide

## Facets
- artifact type: library
- maturity: stable
- function: embedded, sdk, developer-tools
- domain: embedded-systems, iot, hardware
- platform: embedded, iot, cpp
- tags: arduino, esp32, esp-idf, microcontroller, firmware, arduino-core
