Adafruit 0.56" 4-Digit 7-Segment FeatherWing Display - Yellow

The Yellow Adafruit 0.56" 4-Digit 7-Segment Display FeatherWing Combo Pack combines a bright yellow numeric display with an I2C FeatherWing driver, providing four digits, decimal points and colon dots while using just two I2C pins.

One segment? No way dude! 7-Segments for life!

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!

The 7-segment FeatherWing backpack makes it really easy to add a 4-digit numeric display with decimal points and even 'second colon dots' for making a clock.

The LEDs themselves do not connect to the Feather. Instead, a matrix driver chip (HT16K33) does the multiplexing for you. The Feather simply sends I2C commands to the chip to tell it what LEDs to light up, and it is handled for you. This takes a lot of the work and pin-requirements off the Feather. Since it uses only I2C for control, it works with any Feather and can share the I2C pins for other sensors or displays.

The product kit comes with:

• A fully tested and assembled Adafruit 4-Digit 7-Segment LED Matrix Display FeatherWing
  
• Ultra-bright 4-digit 0.56" tall yellow seven-segment display
  
• Two 16-pin headers
  

A bit of soldering is required to attach the matrix onto the FeatherWing, but it's very easy to do and only takes about 5 minutes. Check out Adafruits detailed tutorial for pinouts, assembly, Arduino, CircuitPython usage, and more!
