The Adafruit 0.54" Quad Alphanumeric FeatherWing Display in yellow adds a bright, easy-to-read 4-character 14-segment LED display to any Feather microcontroller. Each character can show full alphanumeric text (A–Z, 0–9) plus symbols, making it ideal for clocks, sensor readouts, status messages, and scrolling text.

The onboard HT16K33 LED driver handles all multiplexing over I2C, requiring just two pins and leaving the rest free for your project. The I2C bus can be shared with other sensors and displays, and the address is selectable from 0x70–0x77 via solder jumpers — allowing up to eight displays on a single bus.
