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.

I am just going to make it clear that the boards are not currently going to come preprogrammed with some kind of serial LCD backpack code or other code. It will be up to you to program it how you please, but all the capabilities are there. I will be posting example code though and hopefully some tutorials to get started.
