With a character height of 0.56 inches, it is suitable for viewing at long distances, making it perfect for scoreboard displays, timers, measurement equipment, and industrial instrumentation.

Each segment is built using high-efficiency LEDs, providing excellent clarity and long operational life. The display is easy to interface using common cathode or common anode configurations (depending on variant). It can be driven using transistor arrays like ULN2803, current-limiting resistors, or display driver ICs such as MAX7219, TM1637, or CD4511.

The ASD-230CI is ideal for both hobbyist and professional applications requiring a robust and readable numeric display.
