Quad Alphanumeric Display - Red 0.54" Digits with I2C Backpack - STEMMA QT / Qwiic

Display numbers and letters elegantly with the Quad Alphanumeric Display in bright red. This super bright display features 0.54" digits with seven red segments on a black surface, making it perfect for viewing from up to 23 feet (7 meters) away. The kit includes two ultra-bright red alphanumeric displays providing a total of 4 digits, a 14-segment LED alphanumeric backpack, and a 5-pin header.

The backpack is stackable and supports up to 8 units sharing the same two I2C wires, thanks to address jumpers on the back. The updated design includes two STEMMA QT connectors compatible with SparkFun Qwiic I2C connectors for easy solderless connections and chainability with other sensors and accessories using compatible cables.

A bit of soldering (about 5 minutes) is required to attach the displays onto the backpack. A detailed tutorial is available to guide you through soldering, wiring, and controlling the display.
