The command interface is compatible with the popular «Matrix Orbital» specifications so this backpack will work perfectly with computer applications or libraries that are expecting a «Matrix» LCD such as «LCD Smartie». We added a few extra commands for the RGB backlight and setting the LCD size. If you don’t want to use the commands, you can just start sending ASCII to the LCD and it will magically appear as typed.
This mini-kit comes with three parts: the Adafruit USB+Serial LCD backpack and a single 16×2 RGB positive backlight LCD, and a strip of header. The LCD must be soldered onto the backpack using the header. This isn’t a difficult task but a soldering iron and solder is required. It’s easy, even for a beginner, to attach the LCD.
We have a full tutorial, including diagrams, testing instructions, and more!
