Achieve clear, reliable data visualization with our Common Cathode (-) 7-Segment LED Display. This essential electronic component features a standard single-digit layout capable of displaying numbers 0-9 and a precise decimal point. Labeled as C.C (Common Cathode), this display is designed for circuits where the negative terminals of all segments are tied together, making it highly compatible with standard sinking-driver microcontrollers and logic ICs.
Common Cathode (-) Configuration: All internal LED cathodes share a single common ground pin, simplifying your wiring and PCB layout.
High-Visibility 7-Segment Layout: Standard eight-part design (7 numeric segments + 1 decimal point) provides sharp, easy-to-read characters.
Industrial Contrast Aesthetic: Crafted with a deep black faceplate and bright white-colored segments for maximum legibility in both low-light and bright environments.
Versatile DIP Footprint: Standardized pin spacing ensures a perfect fit for breadboards, prototype shields, and professional PCB assemblies.
Low Power Operation: Engineered for high efficiency, providing consistent brightness across all segments with minimal current draw.
The LED Display (-) (C.C) is a fundamental building block for digital instrumentation. Whether you are creating a custom digital thermometer, a countdown timer, or an industrial frequency counter, the common cathode architecture provides an intuitive interface for most modern digital logic systems.
Type: LED Display.
Configuration: Common Cathode (-) / C.C.
Digit Count: Single Digit (1 Digit).
Face Color: High-Contrast Black.
How do I wire this display?
For a Common Cathode display, connect the common pin to your circuit's ground (GND). To light a segment, apply a positive voltage ($V_$) to the corresponding segment pin through a current-limiting resistor.
What is the difference between C.C and AK?
C.C (this model) is Common Cathode (-), sharing a negative lead. AK is Common Anode (+), where all segments share a positive lead. Ensure your driver or microcontroller is compatible with the C.C logic.
Is the decimal point functional?
Yes, the display includes a dedicated eighth segment for the decimal point, allowing for precise floating-point value representation.
