Basic I2C HD44780 LCD/Keypad Backpack

 

Practical Maker's I2C HD44780 LCD/Keypad Backpack is a basic, inexpensive little LCD backpack that is unique in that it combines a standard 4x3 keypad input with a standard  HD44780 LCD.  It has all of the necessary housekeeping functions like set cursor, cursor left, cursor right and backspace as well as basic single digit key press input /recognition.  All on a single I2C address using the normal Arduino Wire library.
