Product Description
The 0.56-inch 2-Digit Common Cathode 7-Segment Display is a bright, highly readable numeric display module engineered for digital timers, dual-value counters, instrument panels, and microcontroller instrumentation projects. Featuring two crisp 0.56-inch digits with integrated decimal points, this display delivers excellent visibility across workshop benches while maintaining low power consumption.
Essential for building custom timing devices, dual-digit meters, temperature readouts, and numerical counters, this multiplexed display module combines clean segment separation with standard pinout compatibility for Arduino, ESP32, and PIC microcontrollers.
🔌 Wiring Tip: This is a common cathode display, meaning all the negative common pins (cathodes) for each digit are tied together, while the individual segment lines are driven high. To drive both digits cleanly without ghosting, use multiplexing with current-limiting resistors on the segment or digit lines to protect your microcontroller GPIO pins.
Technical & Architectural Highlights
High-Contrast Numeric Readout: 0.56-inch tall digits provide clear legibility for 2-digit numerical values and measurement counters.
Integrated Decimal Points: Includes built-in decimal points per digit for floating-point values or interval markers.
Multiplexed Pin Configuration: Streamlines microcontroller wiring by sharing segment lines across both digits.
Standard Breadboard Friendly: Clean row layout allows easy insertion into prototype boards and custom PCBs.
