PlatformIO Core is the command-line component of the PlatformIO ecosystem for embedded development. It provides a multi-platform build system, package management, library management with a Library Dependency Finder, and a serial port monitor. Projects can use platformio.ini for declarative configuration across platforms and architectures. The Library Manager accepts the PlatformIO Registry and Git, Mercurial and Subversion repositories. Its pio ci command is intended for build servers, with documented integrations including GitHub Actions, GitLab, CircleCI, Drone, AppVeyor, Shippable and Travis CI. The Python-written tool supports Windows, macOS, Linux, FreeBSD and Linux ARMv6+, and its documented installation options include an installer script, Python Package Manager and Homebrew on macOS. It covers frameworks and SDKs including Arduino, CMSIS, FreeRTOS, Mbed, STM32Cube and Zephyr, plus architectures such as AVR, ESP32, RISC-V and STM32. PlatformIO Core is open source under Apache 2.0 for personal and commercial projects, and the listed free plan costs 0.00 USD per free. Minimal diagnostics and usage sharing is enabled by default.
Who it is for
PlatformIO Core suits embedded developers who want command-line build, package and library tools across its supported host systems. Its documented CI integrations may also suit teams building projects on build servers.
