Description
What's better than a single LED? Lots of LEDs! This assembled Adafruit 0.56" 4-Digit 7-Segment Display with I2C Backpack QT in Green offers a compact and easy-to-use solution for adding a bright, green, 4-digit 7-segment display to your projects. The display comes fully tested and assembled with a pre-soldered ultra-bright 0.56" tall green seven-segment display and includes a 4-pin header for easy connections.
This display is multiplexed and controlled via an I2C interface using a driver chip with a built-in clock, enabling 1/16 step dimming and consistent ultra-bright display output without complex wiring. The backpack includes address-selection jumpers to allow multiple displays to be chained on a single I2C bus. The board features two STEMMA QT connectors compatible with SparkFun Qwiic I2C connectors for solderless wiring to microcontrollers and other accessories.
