16x2 Character LCD

This plate makes it easy to use a 16x2 Character LCD. Most character LCDs use lots of GPIO pins, but since this uses I2C you only need two pins.

The keypad gives you buttons to input to the display and it comes with a python library to make it super easy to program.

Note that the same pinout applies to both positive, negative and normal LCD.
