7-Segment Common Anode Display – Numeric LED Module for Digital Counters and Timers The 7-Segment Common Anode Display is a compact and reliable numeric display module used to represent numbers in digital devices. Each segment of the display is composed of an LED that can be individually controlled to form digits 0–9. With a common anode configuration, this module is ideal for use in microcontroller-based systems, digital clocks, counters, voltmeters, and other embedded electronics applications. Product Specifications Feature Specification Display Type 7-Segment LED (Common Anode) Number of Digits 1 Digit (single digit module) Segment Color Red (other colors optional) Forward Voltage (per segment) 1.8V – 2.2V (typical) Forward Current (per segment) 10mA – 20mA Common Anode Voltage Connect to VCC Package Type DIP-10 or DIP-12 (varies by model) Dimensions Approx. 19mm x 12.5mm x 8mm Mounting Type Through-hole Key Features Easy-to-Read Numeric DisplayDisplays numbers from 0 to 9 using 7 individual LED segments. Common Anode ConfigurationAll anode terminals are connected together, simplifying control with current-limiting resistors and NPN transistors or open-drain outputs. Compact and DurableDesigned for space-efficient integration in both DIY and industrial projects. Low Power ConsumptionEnergy-efficient LED segments make it suitable for battery-powered designs. Wide CompatibilityWorks seamlessly with Arduino, ESP32, STM32, and other microcontrollers. Benefits Versatile Digital ReadoutPerfect for counters, clocks, voltage displays, and timers. Simple Control LogicControl individual segments using microcontroller GPIO pins or driver ICs like 74HC595, CD4511, or MAX7219. Educational UseGreat for learning binary, BCD, and digital electronics in classrooms and hobby projects. Multiple Color OptionsTypically available in red, with green, blue, and yellow options. Applications Digital Clocks and Timers Temperature and Voltage Displays Scoreboards Counter Circuits Basic Digital Interface Projects Learning Modules for Students Wiring Note (Common Anode) Connect the common anode pin to 5V (or your supply voltage). Use current-limiting resistors (220Ω–330Ω) between microcontroller pins and each segment cathode.
