  • Dimensions: 2.1" x 3.2"
  • For use with 16x2 LCD's with the I/O at the top right side
  • Plug and play with any Arduino 'classic' - UNO, duemilanove, diecimilla, etc as well as Arduino Mega R3.
  • Uses only the I2C pins - Analog 4 & 5 on classic Arduinos, Digital 20 and 21 on Arduino Mega R3
19This new 16x2 LCD shield makes it easy to use a 16x2 Character LCD. The 16x2 Character LCD is NOT, repeat, NOT, included 

We really like the range of LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then perhaps another 2 to control the backlight for a total of 8 pins. That's about 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. This is a super slick way to add a display without all the wiring hassle. 

This shield 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. 

The shield is designed for 'classic' Arduinos such as the Uno, Duemilanove, Diecimilla, etc. It will also work perfectly with Arduino Mega R3's. Earlier Mega's have the I2C pins in a different location and will require you to solder two wires from the I2C pins on the shield and plug them into the different I2C locations at Digital 20 & 21. This shield will not fit easily on top of an Arduino Ethernet because of the Ethernet jack height.  

This shield comes as a kit! Included is a high quality, USA-made PCB and all the components (buttons, header etc). An LCD is not included, you will need to order one of our fine 16x2 Character LCDs - just pick up whichever style you like the most (16x2 LCDs)

This kit has only been tested with the LCDs we sell and support, if you use another we will not be able to guarantee it works and we will not be able to troubleshot or support it! 

Assembly is easy, even if you've never soldered before and the kit can be completed in 30 minutes. Complete instructions will be provided with order. 

We will also provide information on an easy-to-use Arduino library that you can easily add to your project. It acts just like the built in LiquidCrystal library,but automatically uses the shield pins. You can also easily query the 5 keypad buttons to get input through the library, so you get extra buttons without using any more pins.
