Blue 7-segment clock display - 0.56 digit height

Blue 7-segment clock display - 0.56 digit height

A bright blue 4-digit seven-segment display perfect for clocks, timers, counters, and numeric readouts. Features decimal points on each digit plus centre colon dots for time-based projects.

Note: This is a raw display requiring external driver circuitry. For easier use, consider our I2C backpack version with built-in LED driver.

Key Features

  • 4-Digit Display – 0.56" digit height for easy readability
  • Bright Blue LEDs – 15mcd brightness
  • Centre Colon – Extra wire for clock-style separator
  • Decimal Points – Available on each digit
  • Adjustable Brightness – Run at lower current to save power or max 20mA for full brightness

Specifications

  • Type: Common cathode, multiplexed
  • Digit Height: 0.56" (14.2mm)
  • Brightness: 15mcd
  • Max Current: ~20mA per segment
  • Colour: Blue

Driving Options

  • 74HC595 shift register for anodes (~15mA each)
  • NPN transistors for cathode switching
  • TPIC6B595 high-power shift register for cathodes (~120mA per digit)
  • 8 microcontroller pins (if available)

Ideal For

  • DIY clocks and timers
  • Score counters
  • Temperature displays
  • Numeric readouts
