Its extreme popularity ensures that no matter which micro controller platform you are using, you will definitely find ready libraries to use this LCD. 

It works of 5v and has a blue backlight which can be switched on and off as desired. The contrast of the screen can also be controlled by varying the voltage at the contrast control pin (pin 3). The display is 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight.
