M7E-20DRN1 application field and working principle

M7E-20DRN1 is a Display Modules - LED Character and Numeric, which is widely used in the fields such as equipment indication, advertising, etc. It has the characteristics of low power consumption, durability, wide viewing angle and high brightness.

M7E-20DRN1 is composed of a module, a display board and a back board. The module has 20 red LED digital tube to form the display content, which can be used to display numbers from 0 to 9, and the display content can be changed by controlling its voltage. The display board includes dot matrix window to display various animation effects. The back board adopts double-sided pluggable terminal block, which can be plugged in tight contact with terminals on the board and can also be unpluggedeasily. In addition, it also comes with an instruction code to explain how to operate.

The working principle of M7E-20DRN1 is based on the chip display principle. The chip on the module contains internal logic circuits, which output the corresponding high/low level signals through two control pins, so that the display content can be accurately determined. A number of logical chips, such as 7441 and 74145, are used to drive the module and display board. To use the device, an external power supply is required to provide power, and the control circuit, such as a microcontroller, is connected to the control pin.

The working principle of M7E-20DRN1 is very simple. Firstly, an appropriate power supply is connected to the chip to provide it with power. Then, the control circuit, such as a microcontroller, is connected to the chip\'s control pins. The control circuit will send out the appropriate logic signals, which will be recognized and processed by the chip, and then the chip will display the corresponding symbols, numbers or words on the display board to achieve the desired effect.

Due to its simple structure, high efficiency and low cost, M7E-20DRN1 is becoming increasingly popular in many fields. It is widely used in equipment indication, advertising, traffic control systems, etc. In addition, its easy installation and operation makes it even more convenient for users to use.
