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
