About this item

The SparkFun COM-18565 Qwiic Alphanumeric Display (White) is a 4-character, 14-segment LED display designed for quick and easy integration into any I²C-based project using SparkFun’s Qwiic Connect System. With bright white characters and a clean display layout, this module is ideal for adding readable alphanumeric output to your electronics projects—such as clocks, status monitors, device identifiers, or interactive interfaces. Powered by the HT16K33 LED driver IC, the display handles all the multiplexing, character decoding, and I²C communication, freeing up processing power on your microcontroller. The display supports a full ASCII character set, including letters, numbers, and symbols, enabling you to easily output names, data values, or short messages. Thanks to the Qwiic system, no soldering is required—just plug and go. For flexibility, traditional I²C pins are also broken out for users who prefer breadboard or custom wiring. The board is compact and stackable, with configurable I²C addresses to support multiple displays on one bus. Whether you're building a user interface or simply want to show sensor data or system status, the COM-18565 offers a clean and professional way to add textual output to your project.
