7 Segment Common Anode Display

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

Key Features

• Easy-to-Read Numeric Display
  Displays numbers from 0 to 9 using 7 individual LED segments.

• Common Anode Configuration

• Compact and Durable
  Designed for space-efficient integration in both DIY and industrial projects.

• Low Power Consumption
  Energy-efficient LED segments make it suitable for battery-powered designs.

• Wide Compatibility
  Works seamlessly with Arduino, ESP32, STM32, and other microcontrollers.

Benefits

• Versatile Digital Readout
  Perfect for counters, clocks, voltage displays, and timers.

• Simple Control Logic
  Control individual segments using microcontroller GPIO pins or driver ICs like 74HC595, CD4511, or MAX7219.

• Educational Use
  Great for learning binary, BCD, and digital electronics in classrooms and hobby projects.

• Multiple Color Options
  Typically available in red, with green, blue, and yellow options.

Applications

• Digital Clocks and Timers
