## What it is
An Arduino core that ports the Arduino development environment to the Raspberry Pi Pico's RP2040 and RP2350 microcontrollers, built on the official Raspberry Pi Pico SDK. It supports a wide range of third-party boards, ARM and RISC-V cores, FreeRTOS with SMP, and wireless features like WiFi and Bluetooth on Pico W variants.

## Use cases
- program a Raspberry Pi Pico with Arduino sketches
- build IoT projects with Pico W WiFi and Bluetooth
- use FreeRTOS with SMP on RP2040
- develop firmware for RP2350 boards
- flash Arduino code to third-party RP2040 boards like Adafruit Feather

## When to choose
- you want the Arduino API and ecosystem on RP2040/RP2350 hardware
- you need broad board support and active maintenance
- you want WiFi/BLE support on Pico W without leaving Arduino

## When to avoid
- you need bare-metal C/C++ with the official Pico SDK directly
- you target microcontrollers other than RP2040/RP2350
- you require Arduino compatibility with other cores' libraries that depend on AVR specifics

## Facets
- artifact type: library
- maturity: active
- function: embedded, sdk, developer-tools
- domain: embedded-systems, hardware, iot
- platform: embedded, iot, cross-platform
- tags: arduino-core, rp2040, rp2350, raspberry-pi-pico, freertos, smp, wifi, bluetooth, risc-v
