Features :

This module is a 12-pin 4-bit common anode digital tube (0.36 inch) display module with clock points. The driver chip is TM1637. Only 2 signal lines are needed to enable the microcontroller to control the 4-bit 8-segment digital tube.

The module features are as follows:

  • The display device is a 4-digit common positive red digital tube
  • Digital tube with 8 levels of grayscale adjustable
  • The 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 is the ground, VCC is the power supply, DIO is the data input and output pin, and CLK is the clock signal pin;

Digital tube: 4-digit 0.36-inch digital tube with common anode and score point, red letters highlighted;

Positioning holes: 4 M2 screw positioning holes with a hole diameter of 2.2mm, making the module easy to install and position, and realizing combination between modules;
