Adafruit 0.56" 4-Digit 7-Segment Display w/I2C Backpack - Yellow

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!
