TM1637 LED Display Module

0.36 4-Digit 7 Segment Red

Description:

The module is a 12-pin 4-digit common anode digital tube (0.36 inch) display module with clock dots. The driver chip is TM1637. Only 2 signal lines are required to enable the single-chip microcomputer to control a 4-digit 8-segment digital tube.

  • 1. The display device is a 4-digit common anode red-digit digital tube, which can be used to display decimals, letters, etc.
  • 2. The digital tube 8 grayscale adjustabley.
  • 3. The control interface level can be 5V or 3.3V .
  • 4. 4 * M2 screw positioning holes for easy installation.

4-Digit 7-Segment Display

The 7-segment displays are actually seven LEDs lined up in a particular pattern (the shape of ‘8’). Each of the seven LEDs is called a segment, which forms part of a numeric digit (both decimal and hex).

In addition to the 4-Digit 7-segments, the module has a ‘colon’ at the center which makes it very easy to create clock or time-based projects.

TM1637 Serial LED Driver

The TM1637 supports many functions – including ON/OFF and brightness control of the LEDs as well as accessing each of the segments. It also allows you to adjust the brightness of the LEDs at software level.

TM1637 Module Pinout

There is a 4-pin right angle male header on the module for making connections. The TM1637 module operates on a supply voltage of 3.3 to 5 volts and communicates via a two-wire bus, so it only requires two data pins plus VCC and ground.

PINOUT

  • GND is a ground pin
  • VCC pin supplies power to the module. Connect it to the 3.3V to 5V power supply
  • DIO is a Data I/O pin. Connect to any digital pin on Arduino.
  • CLK is a clock input pin. Connect to any digital pin on Arduino.
