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

The Adafruit 0.56" 4-Digit 7-Segment FeatherWing Display in blue is an easy-to-use numeric display with decimal points and second colon dots, ideal for clock projects and numeric indicators. This FeatherWing features a multiplexed 7-segment LED matrix controlled by the HT16K33 driver chip, which handles all multiplexing so you only need to communicate via I2C. Compatible with any Feather board, this display shares I2C pins with other sensors or devices.
