AC014 – 4-Digit 7-Segment LED Display, 0.56" rectangular flat format. Displays 0000–9999 with decimal point support on each digit. Ideal for Arduino clocks, counters, and temperature displays.

 

The AC014 Rectangle 0.56 Inch 4-Digit 7-Segment LED Display (MPN: AC014) is a compact, bright numeric display module designed for electronics projects that require a clear digital readout. With four 0.56-inch digits arranged in a flat rectangular housing, it is one of the most widely used display components in DIY electronics, offering a simple multiplexed interface that works directly with microcontrollers.

Key Features

  • 0.56" Digit Height: Large enough to read comfortably from a distance → ideal for panel-mount instruments and clocks
  • 4-Digit Display: Shows values from 0000 to 9999 → covers counters, timers, and 4-digit numeric readouts
  • Decimal Point (DP) per Digit: Each digit has an individual decimal point → enables voltage, temperature, or time readouts with decimals
  • 7-Segment LED Technology: High brightness, low power, long lifespan → reliable for always-on indicator applications
  • Flat Rectangular Form Factor: Space-efficient profile → easy to integrate into enclosures and custom PCBs

Compatibility

  • Arduino UNO / Nano / Mega: Directly compatible via digital I/O pins; typically driven with a shift register (e.g. 74HC595) or a dedicated driver IC (e.g. TM1637, MAX7219) to reduce pin usage.
  • ESP32 / ESP8266: Compatible when used with a driver IC that handles the 3.3 V logic level interface.
  • Raspberry Pi: Usable via driver IC with appropriate GPIO library.

Typical Applications

  • Digital clocks and timers: Display hours/minutes or countdown values — one of the most common maker projects using a 4-digit 7-segment display.
  • Temperature indicators: Show sensor readings (e.g. DS18B20, DHT22) with a decimal point for precision readouts like 23.5°C.
  • Frequency counters: Real-time numeric output for signal measurement projects.
  • Scoreboards and counters: Event-triggered increment/decrement displays for games or industrial counting applications.
  • Voltage / current meters: Display ADC-converted readings from analog sensors with decimal-point formatting.

FAQ

Q: Do I need extra components to connect this display to an Arduino?
A: Yes. A bare 4-digit 7-segment display requires multiplexing logic. Using a driver IC such as the TM1637 or MAX7219 significantly simplifies wiring and reduces the number of GPIO pins needed.

Q: What is the difference between common anode and common cathode?
A: Common cathode shares a ground pin per digit; common anode shares a VCC pin. The wiring and driving logic differ — check your driver IC datasheet to match the correct type.

⚠ Note: This is a bare display component — no driver IC or breakout board is included. A current-limiting resistor or driver IC is required for proper operation. Do not apply voltage directly to LED segments without current limiting.
