 * @brief This class represents the Analog Card.
 * 
 * The analog card has 8 analog inputs accross two banks, and 4 DAC outputs.
 * 
 * @note You do not need to specify the ESPMega I/O Address when creating an instance of this class as there can only be one Analog Card installed in the ESPMegaPRO board.
 * @warning There can only be one Analog Card installed in the ESPMegaPRO board.
