0.36 Inch 4-Digit LED Digital Tube Display Module DC 3.3V-5.5V 4Bits Adjustable Brightness LED Display Board

1.Description:
  It is a 0.36 inch display module.Its driver chip is TM1637,and only 2 signal lines are needed to enable the single-chip microcomputer to control a 4-bit 8-segment digital tube.

2.Feature:
  1).The control interface level supports 5V or 3.3V,and the commonly used connection voltage.
  2).It has 4 screw positioning holes with an aperture of 2.2mm to facilitate the installation and positioning of the modules and realize the combination of modules.
  3).It has 4 pins,easy to connect and easy to use.
  4).It uses a 0.36 inch digital tube with a score point with 4 common anodes.
  5).It uses the TM1637 driver chip,which is stable in use.

4.Overview of Library Routines:
  1).Clock Display:Use the timer 1 of the MCU on the mainboard to time,and let the 4-digit digital tube display.
  2).Number Flow:0-9,A,b,C,d,E,F and other 16 characters flow from right to left.
  3).Stop Watch:Use the timer 1 of the MCU on the mainboard to time,and can cooperate with the button to realize the stopwatch function.

5.Experimental Equipment(you need to prepare by yourself):
  1).1 Arduino-compatible motherboard (those who are not familiar with open source hardware can understand it as Atmega328P MCU development board) and a mini USB cable.
  2).1 4-digit digital tube display module.
  3).4 male-to-female wires,used to connect the control interface of the module and the development board.

6.Experimental steps:
  1).Use 4 male to female wires to connect the 4-digit digital tube display module and the development board.
  2).Module and development board connection interface:
    1).GND(development board)-black line-GND(Module)
    2).5V(development board)-red line-VCC(Module)
    3).D2(development board)-yellow line-DIO(Module)
    4).D3(development board)-white line-CLK(Module)

7.Package:
  1pcs 0.36 Inch Display Module
