Adafruit Industries Adafruit Industries 0.56" 4-Digit 7-Segment FeatherWing Display - Yellow
This is the Yellow Adafruit 0.56" 4-Digit 7-Segment Display w/ FeatherWing Combo Pack! 7-Segment Matrices like these are 'multiplexed' - so to control all the seven-segment LEDs you need 14 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these LED Matrix FeatherWings come in!
