TLDR
Initialize project
$ pio init --board [uno]

Search for boards$ pio boards [pattern]
SYNOPSIS
pio command [options]
DESCRIPTION
platformio is an ecosystem for embedded development. It provides unified tools for building, uploading, and debugging embedded software across many platforms and frameworks.
The tool supports Arduino, ESP32, STM32, and hundreds of other boards with integrated library management and debugging.
PARAMETERS
init
Initialize project.run
Build project.run --target upload
Upload firmware.device monitor
Serial monitor.device list
List devices.lib install
Install library.lib search
Search libraries.boards
List supported boards.debug
Start debugger.test
Run unit tests.-e env
Specific environment.
CONFIGURATION
platformio.ini
Project configuration file defining board targets, frameworks, library dependencies, and build options.~/.platformio/
PlatformIO home directory containing installed platforms, packages, and global settings.PLATFORMIO_CORE_DIR
Environment variable to override the PlatformIO home directory location.
CAVEATS
Initial setup downloads many dependencies. Some boards need drivers. IDE integration varies. Large project builds slow.
HISTORY
PlatformIO was created by Ivan Kravets in 2014 to unify embedded development tooling. It addressed the fragmentation of vendor-specific IDEs and build systems, becoming popular with IoT and maker communities.
