Product Description

The 0.56" 1-Digit Display is a robust solid-state device consisting of 8 individual LEDs (7 for the number segments and 1 for the decimal point). Unlike multi-digit modules, this single-digit version does not require multiplexing, meaning you can drive all segments simultaneously for maximum brightness. It features a black face and white segments, which ensures the red light is sharp and easy to read even in bright environments.

Key Features

  • Direct Drive Capability: Since it only has one digit, you can connect it directly to a microcontroller or a BCD-to-7-segment decoder without complex timing code.

  • High Reliability: LED technology ensures a long operational life of over 50,000 hours with consistent brightness.

  • Standard 10-Pin Layout: The 2.54mm pin pitch fits perfectly into breadboards and standard IC sockets for easy prototyping.

  • Low Power Requirement: Can be powered by a standard 3.3V or 5V rail (with appropriate resistors), making it ideal for battery-operated counters.

  • Uniform Illumination: Each segment is engineered to provide even light distribution, preventing "hot spots" within the digit.

Technical Details

  • Dimensions: 19mm x 12.7mm x 8mm.

  • Peak Wavelength: 635nm (Red).

  • Operating Temperature: -25°C to +85°C.

Prototyping and Engineering Tips from Robogears

  • Resistors are Mandatory: You must use a current-limiting resistor (typically 220Ω to 470Ω) for each segment. Connecting the segments directly to 5V will instantly burn out the LEDs.

  • Identify Your Polarity: * Common Anode (CA): Connect the common pin to 5V; pull segment pins Low (GND) to turn them on.

    • Common Cathode (CC): Connect the common pin to GND; pull segment pins High (5V) to turn them on.

  • Using a Decoder: To save pins on your Arduino (using 4 pins instead of 8), pair this display with a 74HC4511 (for CC) or 74LS47 (for CA) BCD-to-7-segment decoder IC.

  • Dimming: If the display is too bright, you can use PWM (Pulse Width Modulation) on the common pin to adjust the overall brightness through code.

Package Includes

  • 1 x 0.56" Red 1-Digit 7-Segment LED Display

Disclaimer

Always check the part number on the side of the display to verify if it is Common Anode or Common Cathode before wiring. Swapping the logic will prevent the display from lighting up but usually won't damage it if resistors are used.
