| For example, using this module, UART communcation between uC32 and PC can be implemented over USB cable. Connecting the uC32 to the PC creates a new COM port which can be used in a simple terminal application.\\ | For example, using this module, UART communcation between uC32 and PC can be implemented over USB cable.
