4-digit LED display module, red highlights, with adjustable LED brightness and clock point, can display decimals, letters, etc.
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.
The driver IC is TM1637, compatible with Arduino.
The digital display tube can be controlled with only two signal lines, simple and easy to use.
Control interface: a total of 4 pins (GND, VCC, DIO, CLK), GND to ground, VCC for the power supply, DIO for the data input and output pins, CLK for the clock signal pin.
4 M2 screw holes, easy to install, locate and combine modules.
LED Display Module TM1637 0.36” 4-Digit Clock Double Dots 7 Segment Red Digital Tube for Arduino Driver Board
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. 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.
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.
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
