4-Digit 7-Segment Display Module – LED Numeric Display for Arduino, ESP32, and Microcontrollers
The 4-Digit 7-Segment Display Module is a convenient solution for displaying numerical data such as time, counters, temperature, or sensor readings in embedded projects. It features four digits (0–9) with a colon or dot separator, making it ideal for digital clocks, timers, and measurement systems.
 
Key Features:
Displays Four Digits (0–9)
Ideal for numeric values like time, sensor output, counters, etc.
Available in Common Cathode or Anode
Compatible with various driver ICs and microcontroller logic levels.
Bright and Clear Red LEDs
Good visibility under indoor lighting with low power consumption.
Multiplexed Display Control
Reduces the number of microcontroller pins required by scanning one digit at a time.
Driver Compatible (e.g., TM1637 / MAX7219)
Easy to integrate using popular driver ICs or libraries on Arduino and ESP-based platforms.
 
Applications:
Digital clocks and timers
Electronic meters and counters
DIY display panels
Arduino-based temperature or voltage displays
Scoreboards and numeric indicators
Frequency and RPM meters
