# 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.
