The new version of the dot matrix module is compatible with the LCD12864 LCD interface of the development board, and can be seamlessly and unlimitedly cascaded.

 

The price is the price of a single module, select the number according to your needs. With the development of LED technology, more and more shops are beginning to use LED dot matrix screens to release some product information, and learning LED dot matrix application technology is becoming more and more important in the application of single-chip microcomputers. Based on the technology used in dot matrix LED screens commonly used in the market, our shop has successively launched 16×16 dot matrix LED modules, 16×32 dot matrix modules, and 16×64 dot matrix modules for users to learn LED dot matrix application technology. 16*16LED dot matrix integrated module (including drive circuit)

 

This dot matrix display screen is a 16×16 dot matrix LED screen, which can display 1 Chinese character, and can realize the whole line up, curtain in and curtain out, left and right movement of the display mode.

 

The circuit board is a double-sided PCB version. The component welding adopts wave soldering technology. The module consists of 4 dot matrix LEDs, 2 series-in and parallel-out chips 74HC595 for column control, and 2 decoding chips 74HC138 for row control, while 8 are reserved The control port is led out through the pins, and the user can use DuPont wires or other connecting wires to connect to the microcontroller for control.
