Datasheet

Solder all 5 pins!

That's it! now you're ready to run the firmware on your Arduino!

Downloading the Arduino Library

We wrote a basic library to help you work with the alphanumeric backpack. The library is written for the Arduino and

will work with any Arduino as it just uses the I2C pins. The code is very portable and can be easily adapted to any I2C-

capable micro.

Begin by downloading our Adafruit LED Backpack library from github (https://adafru.it/aLI). You can do that by visiting

the github repo and manually downloading or, easier, just click this button to download the zip

https://adafru.it/dxh

Rename the uncompressed folder Adafruit_LEDBackpack and check that the Adafruit_LEDBackpack folder contains

Adafruit_LEDBackpack.cpp and Adafruit_LEDBackpack.h

Place the Adafruit_LEDBackpack library folder your arduinosketchfolder/libraries/ folder.

You may need to create the libraries subfolder if its your first library. Restart the IDE.

We also have a great tutorial on Arduino library installation at:

You'll also need to download the Adafruit GFX library - even though this particular backpack doesn't use it! Its just one

of those Arduino dependencies! You can grab the Adafruit GFX library from github (https://adafru.it/aJa) or download by

clicking below.

https://adafru.it/cBB

Rename the uncompressed folder Adafruit_GFX and check that the Adafruit_GFX folder contains Adafruit_GFX.cpp

and Adafruit_GFX.h

Place the Adafruit_GFX library folder your arduinosketchfolder/libraries/ folder like you did with the LED backpacks
