Adafruit 1.2" 4-Digit 7-Segment Display w/I2C Backpack - Yellow
by Adafruit
SKU CED-1269
We love these big 7-segment displays and use them around our warehouse for displaying important information. They are easy to use and work with Arduino, Raspberry Pi, or just about any microcontroller.
The backpacks use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color (the images above are photographed at the dimmest setting to avoid overloading our camera!), 1/16 step display dimming, all via a simple I2C interface. The backpacks come with address-selection jumpers so you can connect up to 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:
Of course, in classic Adafruit fashion, they also have a detailed tutorial showing you how to solder, wire and control the display. We even wrote very nice libraries for the backpacks so you can get running in under half an hour, displaying numbers on the 7-segment for either Arduino or Raspberry Pi. If you've been eyeing matrix displays but hesitated because of the complexity, his is the solution you've been looking for!
