## Description

The Adafruit 0.56" 4-Digit 7-Segment Display with I2C Backpack in yellow makes it easy to add a bright numeric display to any microcontroller project. The backpack handles all LED multiplexing and driving via I2C, so you only need two data pins to control a full 4-digit display. The HT16K33 driver chip provides constant-current output for consistent brightness, 1/16-step dimming control, and a built-in oscillator — no external components needed. Address-selection jumpers allow up to eight 7-segment displays on a single I2C bus. Key Features HT16K33 I2C Driver – Built-in multiplexing, constant-current drive, and 1/16-step dimming Simple I2C Interface – Only two pins required, with address jumpers for up to 8 displays on one bus Ultra-Bright Yellow LEDs – 0.56" digit height, visible from a distance Arduino and CircuitPython Libraries – Well-documented libraries for quick setup Compact Design – Backpack mounts directly behind the display Also Available Blue Green Red White Also available in a larger 1.2" size, or as a pre-assembled version. Package Contents 1× Adafruit I2C LED backpack (assembled and tested) 1× 0.56" 4-digit 7-segment yellow display 1× 4-pin header Note: A small amount of soldering is required to attach the display to the backpack board.
