The Joystick we added Nokia 5110 LCD and nRF24L01 interface. You can easily develop your Joystick games, and even communicate with each other through wireless nRF24L01.
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.
Note: The Joystick with Nokia5110 can't support standard Arduino board Because of standard Arduino board 3.3v just supply 50mA current, which can't content Nokia5110 backlight's need. But our Freaduino support 800mA current which is far more than Nokia5110's demand.
You can also connect it to other platform by 2.54 mm header.
