The module does not provide a resistive touch screen interface. If the user needs to use a resistive
touch, an external dedicated chip is required. The module can provide an I2C interface.The reference
circuit is as follows:

The module provides a set of I2C interfaces that can be used to connect capacitive touches while
providing the required power and interrupt pins. The default interface pins for capacitive touch
software are defined as follows:
