Adafruit Blue 7-segment clock display - 0.56" digit height

The 4-digit seven-segment display enhances your project with numeric precision and vibrant clarity. Each digit includes a decimal point and an extra wire for center colon-dots, ideal for time-based applications. Designed for versatility, these displays boast a brightness of 15 mcd, adjustable by modulating current from minimal to 20mA for enhanced luminosity.

This common-cathode, multiplexed display is controllable via a 74HC595 shift register or by sparing 8 microcontroller pins, catering to various project needs. Amplify control efficiency by integrating NPN transistors or TPIC6B595, managing up to 120mA per digit seamlessly. While this version requires detailed setup, we recommend the backpack version equipped with an LED driver for simplified deployment.

Featuring a striking blue hue, this display is adaptable to multiple project scales with alternative sizes and colors available to suit your creative requirements. Perfectly suited for crafting clocks, timers, and counters, it provides a reliable and aesthetic numeric output solution.
