The Joystick V2.0 has added Nokia 5110 LCD and nRF24L01 interface. You can easily develop your Joystick games, and even communicate each other with wireless nRF24L01. These pinouts also helps it to easily get associated with other processors which helps to develop an user friendly environment.
The shield sits on top of your Arduino and turns it into a simple controller. 7 momentary push buttons ( 4 big buttons + 2 small buttons + joystick select button ) and a two-axis thumb joystick gives your Arduino functionality on the level of old Nintendo controllers.
The Joystick v 2.0 with Nokia 5110 does not support standard Arduino board Because of standard Arduino board 3.3 v just supply 50mA current, which can't support Nokia5110 backlight need.
