Adafruit RGB LCD I2C Shield Kit 16x2 Char Display Negative

LCD shields are popular expansions for the Arduino. Previously, they required 6 IO pins and an additional 3 IO pins to control an RGB backlight, which already occupied half of the available IO pins on an Arduino UNO.

The new Adafruit I2C LCD Shield now controls the 16x2 character LCD, the 3 backlight pins, and 5 keypad pins via the two I2C pins of the Arduino, keeping all other pins free for your expansions. Furthermore, the two I2C pins can still be used for other I2C devices such as RTCs, memory, and sensors. The RGB backlight can be set to 7 colors: Red, Green, Blue, Yellow, Violet, Cyan, and White.

We offer both "RGB Positive" and "RGB Negative" LCDs in our range. The shield works with all classic Arduinos and compatible clones such as the Uno, Duemilanove, Freaduino, Playduino, and the R3 Mega.

The I2C LCD Shield is a kit. Assembly is very straightforward and can be completed in about 30 minutes, even with minimal soldering skills. On Ladyada's info page, you will find a detailed assembly guide as well as all the software and libraries needed for the shield.
