Providers are extensible service modules responsible for the concrete implementation of a specific I/O type. Multiple providers for the same I/O type can be loaded into a Pi4J context concurrently. For example a “RaspberryPi-DigitalInputProvider” and “GertBoard-DigitalInputProvider” could both be loaded and both providing digital inputs at the same time.
The providers also allow to separate the internal logic of the Pi4J core from the concrete implementation of the board on which they are used.
