Do I need TWR-SER board to run SPO2 demo with K53 MCU?

I have already purchased K53N512 MCU board and MED-SPO2 pulse oximeter dev kit.   Do I also need TWR-SER in order to run the SPO2 demo as suggested in AN4327?  It seems strange because K53 board already has a USB port for IAR debugging and serial communication?
