Description: This is the newest version of our basic I2C LCD interfaces. This version is smaller than ever and includes software controllable LCD back-lighting. It also includes a high quality contrast trimmer pot, no fussing with microscopic screw drivers and trimmer pots that turn 360° even when they aren't designed to. Similar to our older I2C LCD interfaces there are pin outs for up to five push buttons. Note: on the standard configuration only four buttons are available since the circuitry of button 5 is used to control the back-lighting. See the instructions page for how to use button number "5" or back-light control. Version 3 also includes the on board required pull-up resistors for I2C. Now the I2C LCD back-pack is even easier to use, you can connect the back-pack with just two wires directly to your Arduino without the need for a breadboard with pull-up resistors.
- 5V DC
- LCD Back-light control
- Up to five button inputs
- Very small size
- Works with any character LCD
- High quality contrast pot
- On board I2C pull up resistors
- 1 5/8" x 1" (41mm x 25mm)
- ~ 3/8" (9mm) thick
This I2C LCD Interface will work with our older I2C LCD Demo Arduino Sketch but to use the back-light control you will need the updated the newer sketch I2C LCD Board v3 Sketch Demo

This is the assembled version of the I2C LCD Interface (as in the above product photo) but some assembly is required. This module is a BYOH version (bring your own headers). We have not soldered on any pin headers so that you can be sure to fit it onto your LCD.
