8x8 LED Matrix Display on MAX7219 DIP for Arduino

The module is an 8 x 8 LED dot matrix (64 LEDs). The dots on the module board light up red. The module can be used in clock design or as other visual projects on the Arduino platform. Also on the site there is an analogue of the 8 x 8 LED matrix, which is designed on the basis of the MAX7219 SMD chip.

The LED matrix board is designed based on the MAX7219 DIP control IC. The MAX7219 driver controls 64 LEDs separately in a common cathode panel. The module has a Serial 3-Wire interface.

Data transfer to the module chip is carried out via the SPI interface, which is connected using 3 pins. The DIN (data input), CS (module select) and CLK (clock signal) pins are connected to free digital ports on the Arduino board. The matrix is powered by the VCC and GND pins of 5 V.

At the output of the module, there are similar contacts as at the input, which serve to connect the same modules in series. Moreover, since the dimensions of the board in width correspond to the dimensions of the matrix, the modules can be combined into a line, thus increasing the information content of the display.

For further work with the MAX7219 LED matrix, you need to download the LedMatrix library, and then install it yourself.
