/**
 * @brief The base class for all expansion cards
 * 
 * In order to create a new expansion card, you should create a new class that inherits from this class.
 * Your class should implement the following functions:
 * - begin() : Initialize the card
 * - loop() : A function that is called in the main loop
 * - getType() : Get the type of the card, The type should be a unique number between 0 and 255
 * 
 * @warning This class is abstract and should not be instantiated directly.
