PlatformIO Core is a heart of whole PlatformIO ecosystem and consists of
- Multi-platform Build System
- Development platform and package managers
- Library Manager
- Library Dependency Finder (LDF)
- Serial Port Monitor
- Integration components (Cloud & Standalone IDE and Continuous Integration).
PlatformIO Core provides a rich and documented Command Line Interface (CLI). The other PlatformIO-based software and IDEs are based on PlatformIO Core CLI, such as PlatformIO IDE for Atom. In other words, they wrap PlatformIO Core with own GUI.
Please note that you do not need to install PlatformIO Core if you are going to use PlatformIO IDE for Atom. PlatformIO Core is built into PlatformIO IDE and you will be able to use it within PlatformIO IDE Terminal.
Also, PlatformIO IDE allows to install PlatformIO Core Shell Commands
