Edit near the top of Arduino sketch blek2char.ino to select the appropriate target:

/* Uncomment one microprocessor */
//#define BLUEPILL 1
//#define BLACKPILL 1
#define UNO 1 // Arduino Uno, Nano
//#define LEONARDO 1 // Arduino Leonardo, Micro
//#define PROMICRO 1 // Sparkfun ProMicro
//#define MEGA 1 // Arduino Mega 2560
