"This library provides an abstraction over Arduino.h. As long as platform is supported, you can include this library and know that all functions that are usually provided by Arduino.h are available."

This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
