We offer a convenient LCD Keypad shield for Arduino and compatible boards that is quite popular, and it is starting to find use outside of the Arduino world. One example of this is with Raspberry PI, and the method has been documented by Matt W from the Australian Bloody Brilliant Blog (!) in his series of Raspberry Pi articles.
Doing so is easy, and Matt helps out with the pin connections to the Raspberry Pi. The only catch is fitting the shield into a solderless breadboard, however some jumper wires could instead be used for a simpler connection. Nevertheless, without too much effort the display finds a new use with the different platform - for example:
Looking for a rapid-use LCD for your Arduino (or Raspberry Pi) projects? Save time and move forward with the Freetronics LCD & Keypad shield which contains a bright 16x2 character LCD and five buttons that can be read from only one analog input pin:
