Sketch too big
when compiling code for a V6 from https://github.com/reedbn/ubitxv6/ I received this error message
Arduino: 1.8.13 (Windows 10), Board: "Arduino Nano, ATmega328P"
Sketch uses 30750 bytes (100%) of program storage space. Maximum is 30720 bytes.text section exceeds available space in board
Global variables use 819 bytes (39%) of dynamic memory, leaving 1229 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
