It consist of input and output interface to be connected to the microcontroller and cascaded out with multiple dot matrix LED 8×8 display module to make larger LED displays. It comes with 5 pins to be interfaced with microcontroller, which are the VCC, GND, DIN (data in), CS (load) and CLK (clock). This module used MAX7219 chip of serial matrix LED driver which controls the 8×8 red LEDs and drive them at the correct currents. LED Dot Matrix Square white dot matrix common cathode LED square dot matrix 3.0 dot matrix 1388 dot matrix. through hole 32 pins LED matrix display module LED matrix module suface color:black or grey, and LED dot color: white or water clear.
