These 14-segment alphanumeric LED displays can show the full alphabet, numbers, and select symbols in a bright pure green hue. With a 0.54" digit height and 14 mcd brightness, they're readable from up to 7 metres (23 feet) away — perfect for clocks, counters, status readouts, and scrolling text projects.

Each display has two digits with 18 pins (9 per side) at standard 0.1" spacing, making them breadboard-friendly. You get a pack of two displays (four digits total). Pair them with an Adafruit 14-segment LED Alphanumeric Backpack (sold separately) for easy I2C control of each character.

Jargon buster

Plain-language definitions for the technical terms used above.

I2C
I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
LED
A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
