There are two different versions -- v3 and v4.

v3 uses UTFT and UTouch -- which is problematic as the touch function with this display is problematic at best.

v4 uses https://github.com/neu-rah/ArduinoMenu.git

v3 uses the following libraries:

UTFT: http://www.rinkydinkelectronics.com/library.php?id=51

various fonts: http://www.rinkydinkelectronics.com/r_fonts.php

URTouch: http://www.rinkydinkelectronics.com/library.php?id=92
