-If you didn't plan to use DigiUSB in your final sketch, the following proposed alternative consumes less pin than USB and less program memory.\\ Since the last version of <​SoftSerial>​ library (may 2013), <​SoftSerial>​ is an alternative for debugging Digispark just using a single I/O.\\ By declaring a <​SoftSerial>​ object with the __same__ pin for Tx and Rx: it's possible to use a half duplex (request/​response) software serial port using a __single__ I/O. +If you didn't plan to use DigiUSB in your final sketch, the following proposed alternative consumes less pin and  program memory ​than USB.\\ Since the last version of <​SoftSerial>​ library (may 2013), <​SoftSerial>​ is an alternative for debugging Digispark just using a single I/O.\\ By declaring a <​SoftSerial>​ object with the __same__ pin for Tx and Rx: it's possible to use a half duplex (request/​response) software serial port using a __single__ I/O. 
-The external interface is composed of 2 resistors and a regular diode (See below).\\ Please, note this solution requires a native RS232 port (rare today) or a RS232/USB adapter on the development PC.+The external interface is composed of 2 resistors and a regular diode (See below).\\ This approach allows to use the built-in Serial Monitor of the arduino IDE.\\ Please, note this solution requires a native RS232 port (rare today) or a RS232/USB adapter on the development PC.
