Product DescriptionThe 4‑Digit 7‑Segment LED Display is a high-quality numeric module designed to display time, temperature, or counter data. Featuring four individual digits plus decimal points and a colon (depending on the model), this display is perfect for digital clocks and industrial meters. This module uses multiplexing to control all four digits using fewer pins, making it highly efficient for microcontrollers like Arduino and ESP32.Key FeaturesFour Numeric Digits: Displays numbers from 0000 to 9999 with high-contrast red LEDs.Two Size Options: Available in Small (0.36″) for compact devices and Large (0.56″) for standard visibility.Multiplexed Design: Optimized pinout (typically 12 pins) to control 4 digits efficiently.Common Anode/Cathode: Available in both polarities to match your specific driver circuit.Bright Red Illumination: Clear and sharp segments that are easy to read in various lighting.Breadboard Compatible: Standard dual-inline pins for easy prototyping.Typical ApplicationsDigital Clocks & Timers: The industry standard for DIY 24-hour clocks and stopwatches.Digital Voltmeters: Displaying precise voltage or current readings in power supplies.Scoreboards: Keeping track of scores or laps in gaming and sports projects.Counter Modules: Counting units in assembly lines or visitor counters.Temperature Displays: Showing sensor data in home automation systems.Size Selection GuideSmall — 0.36″ (approx. 9mm): Best for tiny handheld gadgets, wearable tech, and minimal panels.Large — 0.56″ (approx. 14mm): The standard size for most desktop devices and control boards.Documents:DatasheetCooking Timer ExampleDisplay Example Code
