What is PlatformIO?

Press about PlatformIO

“Different microcontrollers normally have different developing tools . For instance Arduino rely on Arduino IDE. Few more advanced users set up different graphical interfaces like Eclipse for better project management. Sometimes it may be hard to keep up with different microcontrollers and tools. You probably thought that single unified development tool could be great. Well this is what PlatformIO open source ecosystem is for.

This is cross platform code builder and library manager with platforms like Arduino or MBED support. They took care of toolchains, debuggers, frameworks that work on most popular platforms like Windows, Mac and Linux. It supports more than 200 development boards along with more than 15 development platforms and 10 frameworks. So most of popular boards are covered. They’ve done hard work in organizing and managing hundreds of libraries that can be included in to your project. Also lots of examples allow you to start developing quickly. PlatformIO initially was developed with Command line philosophy. It’s been successfully used with other IDE’s like Eclipse or Visual Studio. Recently they’ve released a version with built in IDE based on Atom text editor”, - [Embedds].


PlatformIO was nominated for the year’s best Software and Tools in the 2015/16 IoT Awards.


  • The main problem which repulses people from the embedded world is a complicated process to setup development software for a specific MCU/board: toolchains, proprietary vendor’s IDE (which sometimes isn’t free) and what is more, to get a computer with OS where that software is supported.
  • Multiple hardware platforms (MCUs, boards) require different toolchains, IDEs, etc, and, respectively, spending time on learning new development environments.
  • Finding proper libraries and code samples showing how to use popular sensors, actuators, etc.
  • Sharing embedded projects between team members, regardless of an operating system they prefer to work with.


PlatformIO is independent of the platform, in which it is running. In fact, the only requirement is Python, which exists pretty much everywhere. What this means is that PlatformIO projects can be easily moved from one computer to another, as well as that PlatformIO allows for the easy sharing of projects between team members, regardless of operating system they prefer to work with. Beyond that, PlatformIO can be run not only on commonly used desktops/laptops but also on the servers without X Window System. While PlatformIO itself is a console application, it can be used in combination with one’s favorite Cloud & Desktop IDE or text editor such as PlatformIO IDE for Atom, CLion, Eclipse, Emacs, NetBeans, Qt Creator, Sublime Text, Vim, Visual Studio, PlatformIO IDE for VSCode, etc.

Alright, so PlatformIO can run on different operating systems. But more importantly, from a development perspective at least, is a list of supported boards and MCUs. To keep things short: PlatformIO supports approximately 200 Embedded Boards and all major Development Platforms.

User SHOULD have a choice

  • Decide which operating system they want to run development process on. You can even use one OS at home and another at work.
  • Choose which editor to use for writing the code. It can be a pretty simple editor or powerful favorite Cloud & Desktop IDE.
  • Focus on the code development, significantly simplifying support for the Development Platforms and MCUs.

How does it work?

Without going too deep into PlatformIO implementation details, work cycle of the project developed using PlatformIO is as follows:

  • Users choose board(s) interested in “platformio.ini” (Project Configuration File)
  • Based on this list of boards, PlatformIO downloads required toolchains and installs them automatically.
  • Users develop code and PlatformIO makes sure that it is compiled, prepared and uploaded to all the boards of interest.
