TM1637 LED Display Module — 4-Bit 7-Segment, 0.36 Inch, Red, 2-Wire Serial Driver for Arduino
The TM1637 4-bit 7-segment LED display module is the most beginner-friendly numeric display solution for Arduino, ESP32, and microcontroller projects. With a simple 2-wire serial interface (CLK + DIO), this module displays 4-digit numbers, clock time, and simple text using just two GPIO pins — no shift registers, no SPI, no complex wiring required.
The bright red 0.36-inch LED digits are clearly visible from across a room, and the built-in colon separator makes this module the natural choice for clock and timer displays. The TM1637 driver IC handles all multiplexing and current control internally, and the popular TM1637Display Arduino library makes integration straightforward for beginners and experienced makers alike.
Key Features
- 4-digit 7-segment display — displays numbers 0–9, letters A–F, and basic symbols
- 2-wire serial interface (CLK + DIO) — only 2 GPIO pins required; minimal wiring
- Built-in colon separator — ideal for HH:MM clock time display
- 0.36-inch digit height — clearly visible from across a room
- Red LED color — high contrast, easy to read in most lighting conditions
- 8 adjustable brightness levels — software-controlled via TM1637 library
- 3.3V and 5V compatible — works with Arduino, ESP32, and Raspberry Pi
Typical Applications
- Digital clock display — HH:MM time display with colon separator
- Countdown timer — kitchen timer, sports timer, and countdown display
- Counter and tally display — event counter, visitor counter, and score display
- Sensor data display — temperature, humidity, and other 4-digit sensor readings
- Arduino beginner projects — easy-to-use display for first Arduino projects
