I would like to use the ChipKit Max32
If you are talking about the interface between the Max32 and the computer running the IDE it uses a USB interface.
The Max32 uses a USB to serial converter chip to convert the serial interface on the PIC32 processor to a USB interface
connected to the computer running the IDE.
gdstew points are valid. You should clearly use the USB for the IDE. The other usage like serial can be handled by a serial to USB bridge of the GPIO pins.
