Adafruit Blue&White 16x2 LCD+Keypad Kit for Raspberry Pi [ADA1115]

Unfortunately, LCDs require quite a few digital pins, 6 to control the LCD and then another 1 to control the backlight for a total of 7 pins. That's nearly all the GPIO available on a Pi! With this in mind, Adafruit devised a Pi plate that lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi! The best part is you don't really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus.

This is a super slick way to add a display without all the wiring hassle. This Pi plate has been updated so the buttons on on the right side, which makes it a little more mechanically stable. It is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer.
