![]() ![]() This is a super slick way to add a display without all the wiring hassle. That's half of the pins available on a classic Arduino! With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield 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 Arduino! 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. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then perhaps another 3 to control the RGB backlight for a total of 9 pins. We really like the range of LCDs we stock in the shop, such as our classic blue & white as well as the fancy RGB negative and RGB positive. This is a library for the Adafruit RGB 16x2 LCD Shield Pick one up at the Adafruit shop! -> This new Adafruit shield makes it easy to use a 16x2 Character LCD.

Tested and works great with the Adafruit Ultimate GPS module using MTK33x9 chipset -> These modules use TTL serial to communicate, 2 pins are required to interface Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
