TM1637 4-Piece 7-Segment Red Display Module

TM1637 4-Piece 7-Segment Red Display Module

The module is a 12-pin display module with a 4-point common digital tube (0.36 inch) with a clock point.
The driver chip is TM1637.
It only needs 2 signal lines to enable MCU to control 4 bit 8 segment digital tube.
Module Features are as follows:
Display device 4 digit yang red digital tube
Digital tube 8-level grayscale adjustable.
Control interface level can be 5V or 3.3V
4 M2 screw positioning holes for easy installation
Control interface a total of 4 pins (GND, VCC, DIO, CLK), GND ground, VCC power supply, DIO data input and output pin, CLK clock signal pin;
Digital tube: 4-digit common anode with a 0.36 inch digital tube with a score dot highlighted in red;
Positioning hole: 4 M2 screw positioning holes, hole diameter 2.2mm, which facilitates the installation and location of the module and realizes the module combination.
Experiment Materials: An Arduino compatible board  (atmega can be understood as an atmega microcontroller development board for those unfamiliar with open source hardware) and a mini USB cable;
14 digit digital tube display module; 4 male-female DuPont lines to connect the control interface of the module and the Arduino development board;
