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.
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.
1).Product Name:0.36 Inch Display Module
2).Working Voltage:DC 3.3V-5.5V
5).Screen Size:0.36 inch
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.
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)
