I know the sain smart 1602 LCD keypad shield will not work with Due since it uses 5V. I wanted to know if anyone has modified the sain smart 1602 LCD keypad shield to work with a 3.3 input voltage.

Do you think I can take the Sain smart board and pull the TC1602 and replaced it with a HD44780 from sparkfun electronics?
