What's better than a single LED? Lots of LEDs! But adding an LED matrix can mean a lot of wiring and space. This little kit makes the whole thing simple and tidy!
 
 Requires a 5V supply
 Constant current drivers for ultra-bright, consistent colour
 1/16 step display dimming
 I2C interface
 Also available as an 8x8 LED matrix in two sizes - small (1.2") and mini (0.7")
 Backpack comes with address-selection jumpers so you can connect up to four mini 8x8's or eight 7-segments (or a combination, such as four mini 8x8's and four 7-segments, etc) on a single I2C bus.
 
 The product kit comes with:
 
 A fully tested and assembled LED backpack
 Ultra-bright 4-digit 0.56" tall seven-segment display
 4-pin header
 
 
 Adafruit have even provided a tutorial showing how to solder, wire and control the display and a library to help you get started!
